Electromagnetic compatibility and Radio spectrum Matters (ERM); Short Range Devices; Road Transport and Traffic Telematics (RTTT); Short range radar equipment operating in the 24 GHz range; Part 1: Technical requirements and methods of measurement (V1.3.1
The present document specifies the technical requirements and methods of measurement for Short Range Devices (SRD) working as broadband devices with at least 500 MHz bandwidth in the 22@000 GHz to 26@65 GHz frequency range intended for Road Transport and Traffic Telematics (RTTT) applications@ such as automotive 24 GHz Short Range Radar (SRR) for e.g. obstacle detection@ stop and go@ blind spot detection@ parking aid@ backup aid@ precrash and other automotive applications. The present document covers transmitters intended to operate in a temporary frequency designation under the 24 GHz ECC decision CEPT/ECC/DEC/(04)10 [10]. The application is also subject to the EU Commission decision on 24 GHz SRR 2005/50/EC [11]. The present document applies to: a) Transmitters in the range from 22@000 GHz to 26@65 GHz operating as broadband devices over the specific bandwidth defined for the individual devices. b) Receivers operating in the range from 22@000 GHz to 26@65 GHz. c) Integrated transceivers. The present document contains the technical characteristics and test methods for short range radar equipment fitted with integral antennas. 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. The present document covers short range radar mobile applications. The present document covers only SRR equipment for road vehicles. The present document complies with field limits for human exposure to electromagnetic fields as provided by the EC Recommendation 1999/519/EC [4] and the methods for compliance demonstration in EN 50371 [12].
