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.
