Naprave kratkega dosega (SRD) - Uporaba sistemov za slikanje pri radarjih za sondiranje tal in zidov (GPR/WPR) - Harmonizirani standard, ki zajema bistvene zahteve člena 3.2 direktive 2014/53/EU
Ta dokument določa zahteve za uporabo sistemov za slikanje pri radarjih za sondiranje tal in zidov.
Radarji za sondiranje tal (GPR) in radarji za sondiranje zidov (WPR) se uporabljajo za raziskovanje in odkrivanje. Področje uporabe je omejeno na radarje za sondiranje tal in radarje za sondiranje zidov, pri čemer je sistem v neposredni bližini materialov, ki se preiskujejo. Ne zajema radarjev, ki se upravljajo iz zračnih ali vesoljskih plovil.
Načini uporabe radarjev za sondiranje tal in radarjev za sondiranje zidov v tem dokumentu niso namenjeni za komunikacijo in uporabljeni signal ne seva v okolje.
OPOMBA: Oprema, zajeta v tem dokumentu, je namenjena za pristojno strokovno osebje.
Ta dokument se uporablja za:
1) radarje za sondiranje tal (GPR), ki delujejo v frekvenčnem območju 30 MHz do 12,4 GHz in ki sevajo neposredno navzdol v tla.
2) radarje za sondiranje zidov (WPR), ki delujejo v frekvenčnem območju 30 MHz do 12,4 GHz in ki sevajo neposredno v »zid«. "Zid" je struktura iz gradbenega materiala, stran mostu, stena v rudniku ali druga fizična struktura, ki absorbira pomemben del signala, ki ga je oddal radar.
Ta oprema:
1) je lahko opremljena z vgrajenimi antenami in je brez antenskih priključkov; ali
2) lahko uporablja različne detektorske glave (antene) z antenskim priključkom, da omogoča delovanje v različnih pasovnih širinah delovnih frekvenc.
Oprema, zajeta v tem dokumentu, deluje v skladu z odločbo ECC/DEC(06)08 »Sklep odbora za elektronske komunikacije z dne 1. decembra 2006 o pogojih za uporabo radijskega spektra z radarji za sondiranje tal in zidov (GPR/WPR)« [i.2].

1 Scope
The present document specifies the requirements for Ground- and Wall- Probing Radar imaging systems applications.
Ground Probing Radars (GPR) and Wall Probing Radars (WPR) are used in survey and detection applications.
The scope is limited to GPR and WPR radars, in which the system is in close proximity to the materials being
investigated. It does not include radars operated from aircraft or spacecraft.
The GPR/WPR applications in the present document are not intended for communications purposes, and the intended
signal is not radiated into free space.
NOTE: Equipment covered by the present document is intended to be used by competent professional personnel.
The present document applies to:
1) Ground Probing Radars (GPR) operating over approximately one decade in the frequency range 30 MHz to
12,4 GHz radiating directly downwards into the ground.
2) Wall Probing Radars (WPR) operating in the frequency range 30 MHz to 12,4 GHz radiating directly into a
"wall". The "wall" is a building material structure, the side of a bridge, the wall of a mine or another physical
structure that absorbs a significant part of the signal transmitted by the radar.
These equipment can either:
1) be fitted with integral antennas and without antenna connector; or
2) use different imaging heads (antennas) with an antenna connector, to allow operation at different operating
bandwidths frequencies.
Equipment covered by the present document operates in accordance with ECC/DEC(06)08 "ECC Decision of
1 December 2006 on the conditions for use of the radio spectrum by Ground- and Wall- Probing Radar (GPR/WPR)
imaging systems" [i.2].
These radio equipment types are capable of operating in all or part of the frequency bands given in table 1.
Table 1: Permitted ranges of operation
Permitted range of operation (note 1)
Transmit 30 MHz to 12,4 GHz
Receive 30 MHz to 12,4 GHz
Intended ranges of operation (preferred range of operating bandwidth) (note 2)
Transmit 30 MHz to 12,4 GHz
Receive 30 MHz to 12,4 GHz
NOTE 1: Limits in table 2, clause 4.3.4 are to be met.
NOTE 2: This is the preferred range for the operating bandwidth, as defined in clause 4.3.1.
The present document does not apply to radio equipment for which a specific Harmonised EN applies as such
Harmonised EN may specify additional EN requirements relevant to the presumption of conformity under article 3.2 of
the Directive 2014/53/EU [i.5].

4 Technical requirements specifications
4.1 Environmental conditions
The technical requirements of the present document apply under the environmental profile for operation of the
equipment, which shall be declared by the supplier. The equipment shall comply with all the technical requirements of
the present document at all times when operating within the boundary limits of the declared operational environmental
profile. The normal test conditions are defined in clause 5.4.3 of ETSI EN 303 883 [1].
4.2 General
UWB devices in the scope of the present document can operate in a broad permitted range of frequencies from 30 MHz
to 12,4 GHz, as defined in table 1 of the present document. The intended range of operation gives the preferred range of
operational frequencies for the UWB operation based on the allowed spectrum mask with increase permitted emission
levels in the intended range of operation.
In order to clearly identify the required limits and thus measurement procedures it is essential to define the operational
bandwidth of the UWB equipment under test, The operating bandwidth of the UWB equipment under test shall be
the -10 dBc bandwidth of the intended UWB signal under normal operational conditions as defined in clause 4.3.1.
A single UWB device can have more than one operational bandwidth, for instance. One with a UWB operational
bandwidth in the lower frequency range and one in the upper frequency range. All UWB related emissions shall be
measured in the identified operational bandwidth of the UWB device under test. The required mitigation techniques are
only valid in the operational bandwidth.
The RX interference signal handling is focused in the operational bandwidth and some clearly identified frequencies
outside the operational bandwidth(s), see clause 4.4.3.
RX interference signal handling on the operating bandwidth and at defined frequencies below and above the operating
range limits
The test of required mitigation techniques is only relevant inside the operating bandwidth(s).

4.3 Transmitter Conformance Requirements
4.3.1 Operating Bandwidth
4.3.1.1 Applicability
This requirement shall apply to all DUT.
4.3.1.2 Description
GPR/WPR applications are not intended for communications purposes. Their intended usage excludes radiation into the
free space and this should be avoided due to a proper mechanism (see clause 4.7.7).
For these applications, the operating bandwidth(s) is/are the -10 dBc bandwidth(s) of effective emissions radiated into
the air by the equipment.
4.3.1.3 Limits
Any operating bandwidth of all the DUT shall lie within one permitted frequency range of operation of the device (see
table 1) and shall be > 50 MHz.
4.3.1.4 Conformance
The conformance test suite for operating bandwidth shall be as defined in clause 6.5.3 of the present document.
Conformance shall be established under normal test conditions (see clause 4.1).
The interpretation of the results for the measurements uncertainty shall be as given in clause 5.3.
4.3.2 Maximum value of mean power spectral density
This requirement does not apply to any DUT.
4.3.3 Maximum value of peak power
This requirement does not apply to any DUT.
4.3.4 Exterior Limits
4.3.4.1 Applicability
This requirement shall apply to all DUT.
4.3.4.2 Description
The emissions into the air resulting from the operation of GPR/WPR imaging systems are defined as those emissions
radiated in all directions above the ground from the GPR/WPR equipment, including direct emissions from the
housing/structure of the equipment and emissions reflected or passing through the media under inspection; they are
therefore dependent on the operational conditions and are meaningful only if the GPR/WPR are coupled with the
material being investigated.
4.3.4.3 Limits
The effective radiated power of any emission from GPR/WPR shall not exceed the values given in table 2.
Table 2: Power limits of radiated emissions [i.2]
Frequency range Peak power limit values for emission
(MHz)
30 to 230 -44,5 dBm/120 kHz (e.r.p)
> 230 to 1 000 -37,5 dBm/120 kHz (e.r.p)
> 1 000 to 18 000 -30 dBm/MHz (e.i.r.p.)

4.4.2 Receiver spurious emissions
Receiver spurious emissions are measured as part of the emissions resulting from the operation of GPR/WPR imaging
systems, see clause 4.3.4.
4.4.3 Receiver interference handling
4.4.3.1 Applicability
This requirement shall apply to all DUT.
4.4.3.2 Description
Interferer signal handling, defined as the capability of the device to operate as intended in coexistence with interferers,
is the receiver parameter for UWB applications.
Operation as intended is evaluated using a performance criterion. For common applications, recommended performance
criteria and test cases are defined in clause 9.4 of ETSI TS 103 361 [2]. The performance criterion shall be stated in the
user manual (see clause 9.2.2 of ETSI TS 103 361 [2]).

1 Scope
The present document specifies the requirements for Ground- and Wall- Probing Radar imaging systems applications.
Ground Probing Radars (GPR) and Wall Probing Radars (WPR) are used in survey and detection applications.
The scope is limited to GPR and WPR radars, in which the system is in close proximity to the materials being
investigated. It does not include radars operated from aircraft or spacecraft.
The GPR/WPR applications in the present document are not intended for communications purposes, and the intended
signal is not radiated into free space.
NOTE: Equipment covered by the present document is intended to be used by competent professional personnel.
The present document applies to:
1) Ground Probing Radars (GPR) operating in the frequency range 30 MHz to 12,4 GHz radiating directly
downwards into the ground.
2) Wall Probing Radars (WPR) operating in the frequency range 30 MHz to 12,4 GHz radiating directly into a
"wall". The "wall" is a building material structure, the side of a bridge, the wall of a mine or another physical
structure that absorbs a significant part of the signal transmitted by the radar.
These equipment can either:
1) be fitted with integral antennas and without antenna connector; or
2) use different imaging heads (antennas) with an antenna connector, to allow operation at different operating
bandwidths frequencies.
Equipment covered by the present document operates in accordance with ECC/DEC(06)08 "ECC Decision of
1 December 2006 on the conditions for use of the radio spectrum by Ground- and Wall- Probing Radar (GPR/WPR)
imaging systems" [i.2].
These radio equipment types are capable of operating in all or part of the frequency bands given in table 1.
Table 1: Permitted ranges of operation
Permitted range of operation
Transmit 30 MHz to 12,4 GHz
Receive 30 MHz to 12,4 GHz
NOTE 1: Limits in table 2, clause 4.3.4 are to be met.
NOTE 2: The frequency usage conditions for GPR/WPR are not fully harmonised in the EU and CEPT. Some
National Regulatory Authorities (NRAs) may not have a general frequency allocation for GPR/WPT and may
have established individual licensing requirements (e.g. registration of the user). Annex 2 of [i.2] gives some
guidance to administrations.

4 Technical requirements specifications
4.1 Environmental conditions
The technical requirements of the present document apply under the environmental profile for operation of the
equipment, which shall be declared by the manufacturer. The equipment shall comply with all the technical
requirements of the present document at all times when operating within the boundary limits of the declared operational
environmental profile. The normal test conditions are defined in clause 5.4.3 of ETSI EN 303 883 [1].
ETSI
10 Final draft ETSI EN 302 066 V2.1.1 (2016-10)
4.2 General
UWB devices in the scope of the present document can operate in a broad permitted range of frequencies from 30 MHz
to 12,4 GHz, as defined in table 1.
In order to clearly identify the required limits and thus measurement procedures it is essential to define the operational
bandwidth of the UWB equipment under test, The operating bandwidth of the UWB equipment under test shall be
the -10 dBc bandwidth of the intended UWB signal under normal operational conditions as defined in clause 4.3.1.
A single UWB device can have more than one operational bandwidth. All UWB related emissions shall be measured in
the identified operational bandwidth of the UWB device under test. The required mitigation techniques are only valid in
the operational bandwidth.
The RX interference signal handling deals with the performance of the receiver and is focused on interference signals in
the operational bandwidth and on some clearly identified frequencies outside the operational bandwidth(s), see
clause 4.4.3.
4.3 Transmitter Conformance Requirements
4.3.1 Operating Bandwidth
4.3.1.1 Applicability
This requirement shall apply to all DUT.
4.3.1.2 Description
The operating bandwidth(s) of GPR/WPR is/are the -10 dBc bandwidth(s) of effective emissions radiated into the air by
the equipment.
4.3.1.3 Limits
Any operating bandwidth of all the DUT shall lie within the permitted frequency range of operation of the device (see
table 1) and shall be > 50 MHz.
4.3.1.4 Conformance
The conformance test suite for operating bandwidth shall be as defined in clause 6.5.3 of the present document.
Conformance shall be established under normal test conditions (see clause 4.1).
The interpretation of the results for the measurements uncertainty shall be as given in clause 5.3.
4.3.2 Maximum value of mean power spectral density
Intentional emissions can’t be tested due to the nature of the GPR/WPR applications and thus only unintentional
emissions into the air will be tested (see clause 4.3.4 on exterior limit).
4.3.3 Maximum value of peak power
Intentional emissions cannot be tested due to the nature of the GPR/WPR applications and thus only unintentional
emissions into the air will be tested (see clause 4.3.4 on exterior limit).
ETSI
11 Final draft ETSI EN 302 066 V2.1.1 (2016-10)
4.3.4 Exterior Limits
4.3.4.1 Applicability
This requirement shall apply to all DUT.
4.3.4.2 Description
The emissions into the air resulting from the operation of GPR/WPR imaging systems are defined as those emissions
radiated in all directions above the ground from the GPR/WPR equipment, including direct emissions from the
housing/structure of the equipment and emissions reflected or passing through the media under inspection; they are
therefore dependent on the operational conditions and are meaningful only if the GPR/WPR are coupled with the
material being investigated.
4.3.4.3 Limits
The effective radiated power of any emission from GPR/WPR shall not exceed the values given in table 2.
Table 2: Power limits of radiated emissions [i.2]
Frequency range Peak power limit values for emission
(MHz)
30 to 230 -44,5 dBm/120 kHz (e.r.p)
> 230 to 1 000 -37,5 dBm/120 kHz (e.r.p)
> 1 000 to 18 000 -30 dBm/MHz (e.i.r.p.)
The maximum mean e.i.r.p. spectral density shall not exceed the values in table F.1 ([i.2]) and shall be calculated as set
out in annex F.
4.3.4.4 Conformance
The conformance test suite for Exterior Limit shall be as defined in clause 6.5.6.
The maximum mean e.i.r.p. spectral density which is based on the peak values measured according to clause 6.5.6 shall
be calculated as set out in annex F and shall not exceed the values in table F.1 ([i.2]).
Conformance shall be established under normal test conditions (see clause 4.1).
The interpretation of the results for the measurements uncertainty shall be as given in clause 5.3.
4.3.5 Total Power
This requirement does not apply to any DUT.

7 ETSI EN 302 066 V2.1.1 (2017-01)
1 Scope
The present document specifies the requirements for Ground- and Wall- Probing Radar imaging systems applications.
Ground Probing Radars (GPR) and Wall Probing Radars (WPR) are used in survey and detection applications.
The scope is limited to GPR and WPR radars, in which the system is in close proximity to the materials being
investigated. It does not include radars operated from aircraft or spacecraft.
The GPR/WPR applications in the present document are not intended for communications purposes, and the intended
signal is not radiated into free space.
NOTE: Equipment covered by the present document is intended to be used by competent professional personnel.
The present document applies to:
1) Ground Probing Radars (GPR) operating in the frequency range 30 MHz to 12,4 GHz radiating directly
downwards into the ground.
2) Wall Probing Radars (WPR) operating in the frequency range 30 MHz to 12,4 GHz radiating directly into a
"wall". The "wall" is a building material structure, the side of a bridge, the wall of a mine or another physical
structure that absorbs a significant part of the signal transmitted by the radar.
These equipment can either:
1) be fitted with integral antennas and without antenna connector; or
2) use different imaging heads (antennas) with an antenna connector, to allow operation at different operating
bandwidths frequencies.
Equipment covered by the present document operates in accordance with ECC/DEC(06)08 "ECC Decision of
1 December 2006 on the conditions for use of the radio spectrum by Ground- and Wall- Probing Radar (GPR/WPR)
imaging systems" [i.2].
These radio equipment types are capable of operating in all or part of the frequency bands given in table 1.
Table 1: Permitted ranges of operation
Permitted range of operation
Transmit 30 MHz to 12,4 GHz
Receive 30 MHz to 12,4 GHz
NOTE 1: Limits in table 2, clause 4.3.4 are to be met.
NOTE 2: The frequency usage conditions for GPR/WPR are not fully harmonised in the EU and CEPT. Some
National Regulatory Authorities (NRAs) may not have a general frequency allocation for GPR/WPT and may
have established individual licensing requirements (e.g. registration of the user). Annex 2 of [i.2] gives some
guidance to administrations.

4 Technical requirements specifications
4.1 Environmental conditions
The technical requirements of the present document apply under the environmental profile for operation of the
equipment, which shall be declared by the manufacturer. The equipment shall comply with all the technical
requirements of the present document at all times when operating within the boundary limits of the declared operational
environmental profile. The normal test conditions are defined in clause 5.4.3 of ETSI EN 303 883 [1].
4.2 General
UWB devices in the scope of the present document can operate in a broad permitted range of frequencies from 30 MHz
to 12,4 GHz, as defined in table 1.
In order to clearly identify the required limits and thus measurement procedures it is essential to define the operational
bandwidth of the UWB equipment under test, The operating bandwidth of the UWB equipment under test shall be
the -10 dBc bandwidth of the intended UWB signal under normal operational conditions as defined in clause 4.3.1.
A single UWB device can have more than one operational bandwidth. All UWB related emissions shall be measured in
the identified operational bandwidth of the UWB device under test. The required mitigation techniques are only valid in
the operational bandwidth.
The RX interference signal handling deals with the performance of the receiver and is focused on interference signals in
the operational bandwidth and on some clearly identified frequencies outside the operational bandwidth(s), see
clause 4.4.3.
ETSI
10 ETSI EN 302 066 V2.1.1 (2017-01)
4.3 Transmitter Conformance Requirements
4.3.1 Operating Bandwidth
4.3.1.1 Applicability
This requirement shall apply to all DUT.
4.3.1.2 Description
The operating bandwidth(s) of GPR/WPR is/are the -10 dBc bandwidth(s) of effective emissions radiated into the air by
the equipment.
4.3.1.3 Limits
Any operating bandwidth of all the DUT shall lie within the permitted frequency range of operation of the device (see
table 1) and shall be > 50 MHz.
4.3.1.4 Conformance
The conformance test suite for operating bandwidth shall be as defined in clause 6.5.3 of the present document.
Conformance shall be established under normal test conditions (see clause 4.1).
The interpretation of the results for the measurements uncertainty shall be as given in clause 5.3.
4.3.2 Maximum value of mean power spectral density
Intentional emissions can’t be tested due to the nature of the GPR/WPR applications and thus only unintentional
emissions into the air will be tested (see clause 4.3.4 on exterior limit).
4.3.3 Maximum value of peak power
Intentional emissions cannot be tested due to the nature of the GPR/WPR applications and thus only unintentional
emissions into the air will be tested (see clause 4.3.4 on exterior limit).
4.3.4 Exterior Limits
4.3.4.1 Applicability
This requirement shall apply to all DUT.
4.3.4.2 Description
The emissions into the air resulting from the operation of GPR/WPR imaging systems are defined as those emissions
radiated in all directions above the ground from the GPR/WPR equipment, including direct emissions from the
housing/structure of the equipment and emissions reflected or passing through the media under inspection; they are
therefore dependent on the operational conditions and are meaningful only if the GPR/WPR are coupled with the
material being investigated.
4.3.4.3 Limits
The effective radiated power of any emission from GPR/WPR shall not exceed the values given in table 2.

ETSI ETSI EN 302 066 V2.1.1 (2017-01) 7 1 Scope The present document specifies the requirements for Ground- and Wall- Probing Radar imaging systems applications. Ground Probing Radars (GPR) and Wall Probing Radars (WPR) are used in survey and detection applications. The scope is limited to GPR and WPR radars, in which the system is in close proximity to the materials being investigated. It does not include radars operated from aircraft or spacecraft. The GPR/WPR applications in the present document are not intended for communications purposes, and the intended signal is not radiated into free space.
NOTE: Equipment covered by the present document is intended to be used by competent professional personnel. The present document applies to: 1) Ground Probing Radars (GPR) operating in the frequency range 30 MHz to 12,4 GHz radiating directly downwards into the ground. 2) Wall Probing Radars (WPR) operating in the frequency range 30 MHz to 12,4 GHz radiating directly into a "wall". The "wall" is a building material structure, the side of a bridge, the wall of a mine or another physical structure that absorbs a significant part of the signal transmitted by the radar. These equipment can either: 1) be fitted with integral antennas and without antenna connector; or 2) use different imaging heads (antennas) with an antenna connector, to allow operation at different operating bandwidths frequencies. Equipment covered by the present document operates in accordance with ECC/DEC(06)08 "ECC Decision of 1 December 2006 on the conditions for use of the radio spectrum by Ground- and Wall- Probing Radar (GPR/WPR) imaging systems" [i.2]. These radio equipment types are capable of operating in all or part of the frequency bands given in table 1. Table 1: Permitted ranges of operation Permitted range of operation Transmit 30 MHz to 12,4 GHz Receive 30 MHz to 12,4 GHz NOTE 1: Limits in table 2, clause 4.3.4 are to be met. NOTE 2: The frequency usage conditions for GPR/WPR are not fully harmonised in the EU and CEPT. Some National Regulatory Authorities (NRAs) may not have a general frequency allocation for GPR/WPT and may have established individual licensing requirements (e.g. registration of the user). Annex 2 of [i.2] gives some guidance to administrations.

The equipment shall comply with all the technical requirements of the present document at all times when operating within the boundary limits of the declared operational environmental profile. The normal test conditions are defined in clause 5.4.3 of ETSI EN 303 883 [1]. 4.2 General UWB devices in the scope of the present document can operate in a broad permitted range of frequencies from 30 MHz to 12,4 GHz, as defined in table 1. In order to clearly identify the required limits and thus measurement procedures it is essential to define the operational bandwidth of the UWB equipment under test, The operating bandwidth of the UWB equipment under test shall be the -10 dBc bandwidth of the intended UWB signal under normal operational conditions as defined in clause 4.3.1.
A single UWB device can have more than one operational bandwidth. All UWB related emissions shall be measured in the identified operational bandwidth of the UWB device under test. The required mitigation techniques are only valid in the operational bandwidth. The RX interference signal handling deals with the performance of the receiver and is focused on interference signals in the operational bandwidth and on some clearly identified frequencies outside the operational bandwidth(s), see clause 4.4.3.

Conformance shall be established under normal test conditions (see clause 4.1). The interpretation of the results for the measurements uncertainty shall be as given in clause 5.3. 4.3.2 Maximum value of mean power spectral density Intentional emissions can’t be tested due to the nature of the GPR/WPR applications and thus only unintentional emissions into the air will be tested (see clause 4.3.4 on exterior limit). 4.3.3 Maximum value of peak power Intentional emissions cannot be tested due to the nature of the GPR/WPR applications and thus only unintentional emissions into the air will be tested (see clause 4.3.4 on exterior limit). 4.3.4 Exterior Limits 4.3.4.1 Applicability This requirement shall apply to all DUT. 4.3.4.2 Description The emissions into the air resulting from the operation of GPR/WPR imaging systems are defined as those emissions radiated in all directions above the ground from the GPR/WPR equipment, including direct emissions from the housing/structure of the equipment and emissions reflected or passing through the media under inspection; they are therefore dependent on the operational conditions and are meaningful only if the GPR/WPR are coupled with the material being investigated. 4.3.4.3 Limits The effective radiated power of any emission from GPR/WPR shall not exceed the values given in table 2.
