Introduction
The present document, together with ETSI EN 303 396 [1], covers the assessment of certain types of equipment as
defined herein.

ETSI

---------------------- Page: 6 ----------------------
7 ETSI EN 301 091-1 V2.1.1 (2017-01)
1 Scope
The present document specifies technical characteristics and methods of measurements for radar equipment for ground
based vehicle applications in the frequency range from 76 GHz to 77 GHz. It covers integrated transceivers and separate
transmit/receive modules.
Also the present document specifies the requirements for Short Range Devices (SRD) intended for the use in ground
based vehicles. Example applications are: Adaptive Cruise Control (ACC), Collision Warning, Anti-Collision (AC)
systems, obstacle detection, Stop and Go, blind spot detection, parking aid, backup aid and other future applications.
NOTE 1: The definition of "ground based vehicle" includes but is not limited to passenger cars, busses, trucks, rail
engines, ships, aircraft while taxing.
NOTE 2: High safety ratings (e.g. Euro NCAP) can only be obtained if such radar based safety applications are
installed in a vehicle.
NOTE 3: Euro NCAP organizes crash-tests and provides motoring consumers with a realistic and independent
assessment of the safety performance of some of the most popular cars sold in Europe.
Established in 1997, Euro NCAP is composed of seven European Governments as well as motoring and
consumer organizations in every European country.
The present document contains the technical characteristics and test methods for ground based vehicle radar equipment
fitted with integral antennas operating in the frequency range from 76 GHz to 77 GHz and references CEPT/ERC/ECC
Recommendation 70-03 [i.1] and EC DEC 2013/752/EU [i.2].
The present document does not necessarily include all the characteristics which may be required by a user, nor does it
necessarily represent the optimum performance achievable.
In case of differences (for instance concerning special conditions, definitions, abbreviations) between the present
document and ETSI EN 303 396 [1], the provisions of the present document take precedence.
These radio equipment types are capable of operating in all or part of the frequency bands given in table 1.
Table 1: Permitted range of operation [i.2]
Permitted range of operation
Transmit 76 GHz to 77 GHz
Receive 76 GHz to 77 GHz

The present document covers the essential requirements of article 3.2 of Directive 2014/53/EU [i.3] under the
conditions identified in annex A.

1 Scope
The present document applies to radar equipment for ground based vehicle applications in the frequency range from
76 GHz to 77 GHz. It covers integrated transceivers and separate transmit/receive modules.
Also the present document specifies the requirements for Short Range Devices (SRD) intended for the use in ground
based vehicles. Example applications are: Adaptive Cruise Control (ACC), Collision Warning, Anti-Collision (AC)
systems, obstacle detection, Stop and Go, blind spot detection, parking aid, backup aid and other future applications.
NOTE 1: High safety ratings (e.g. EURO NCAP) can only be obtained if such radar based safety applications are
installed in a vehicle. The definition of "ground based vehicle" includes but is not limited to passenger
cars, busses, trucks, rail engines, ships, aircraft while taxing.
NOTE 2: EURO ENCAP: Euro NCAP organizes crash-tests and provides motoring consumers with a realistic and
independent assessment of the safety performance of some of the most popular cars sold in Europe.
Established in 1997, Euro NCAP is composed of seven European Governments as well as motoring and
consumer organizations in every European country.
The present document applies to:
• equipment with an integral antenna;
• ground based vehicle applications only;
• operating in the frequency range from 76 GHz to 77 GHz.
The present document contains the technical characteristics and test methods for ground based vehicle radar equipment
fitted with integral antennas operating in the frequency range from 76 GHz to 77 GHz and references CEPT/ERC/ECC
Recommendation 70-03 [i.1] and EC DEC (2013/752/EU [i.2]).
The present document does not necessarily include all the characteristics which may be required by a user, nor does it
necessarily represent the optimum performance achievable.
In case of differences (for instance concerning special conditions, definitions, abbreviations) between the present
document and ETSI EN 303 396 [1], the provisions of the present document take precedence.
These radio equipment types are capable of operating in all or part of the frequency bands given in table 1.
Table 1: Permitted range of operation [i.2]
Permitted range of operation
Transmit 76 GHz to 77 GHz
Receive 76 GHz to 77 GHz

The present document contains requirements to demonstrate that radio equipment both effectively uses and supports the
efficient use of radio spectrum in order to avoid harmful interference.
