Introduction
GPR and WPR radars are imaging systems designed to operate while in contact with, or in close proximity to the
ground or the wall, and their emissions are directed into the ground or wall (e.g. measured by a proximity sensor or
imposed by the mechanical design).
The GPR/WPR applications in the present document are not intended for communications purposes, and the intended
signal is not radiated into free space. 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 (referred in ECC/DEC/(06)08 [i.2] and in the present document as "undesired emissions"); they
are therefore dependent on the operational conditions and are meaningful only if the GPR/WPR are coupled with the
material being investigated. Figure 1 shows the scenario to be considered for the emissions radiated into the air by
GPR/WPR.

Figure 1: Hatched area around the GPR/WPR shows the emissions
to be considered in this clause

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.These do
not include radars operated from aircraft or spacecraft.
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.
NOTE 1: Equipment covered by the present document operates in accordance with ECC/DEC(06)08 [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
ECC/DEC/(06)08 [i.2] gives some guidance to administrations.

NOTE 2: The relationship between the present document and essential requirements of article 3.2 of Directive
2014/53/EU [i.1] is given in annex A.

Introduction
GPR and WPR radars are imaging systems designed to operate while in contact with, or in close proximity to the
ground or the wall, and their emissions are directed into the ground or wall (e.g. measured by a proximity sensor or
imposed by the mechanical design).
The GPR/WPR applications in the present document are not intended for communications purposes, and the intended
signal is not radiated into free space. 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 (referred in ECC/DEC/(06)08 [i.2] and in the present document as "undesired emissions"); they
are therefore dependent on the operational conditions and are meaningful only if the GPR/WPR are coupled with the
material being investigated. Figure 1 shows the scenario to be considered for the emissions radiated into the air by
GPR/WPR.

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.These do
not include radars operated from aircraft or spacecraft.
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.
NOTE 1: Equipment covered by the present document operates in accordance with ECC/DEC(06)08 [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
ECC/DEC/(06)08 [i.2] gives some guidance to administrations.

NOTE 2: The relationship between the present document and essential requirements of article 3.2 of Directive
2014/53/EU [i.1] is given in annex A.

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, which are imaging systems are designed to operate while in contact with,

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, which are imaging systems are designed to operate while in contact with,
or in close proximity to the ground or the wall, and their emissions being directed into the ground or wall (e.g. measured
by a proximity sensor or imposed by the mechanical design). 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.
The emissions into the air resulting from the operation of GPR/WPR imaging systems are therefore 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 (referred
in ECC/DEC/(06)08 [i.2] and in the present document as "undesired emissions"); they are therefore dependent on the
operational conditions and are meaningful only if the GPR/WPR are coupled with the material being investigated.
Figure 1 shows the scenario to be considered for the emissions radiated into the air by GPR/WPR.

Figure 1: Hatched area around the GPR/WPR shows the emissions
to be considered in this clause
NOTE 1: 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.
NOTE 2: Equipment covered by the present document operates in accordance with ECC/DEC(06)08 [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
ECC/DEC/(06)08 [i.2] gives some guidance to administrations.

NOTE 3: The relationship between the present document and essential requirements of article 3.2 of Directive
2014/53/EU [i.1] is given in annex A.
