scope:

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 26,625 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 as defined in a forthcoming decision of CEPT/ECC. The application is also subject to a forthcoming EU Commission decision on 24 GHz SRR. The present document applies to:

a) Transmitters in the range from 22,000 GHz to 26,625 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 26,625 GHz.

c) Integrated transceivers.

The present document contains the technical characteristics and test methods for short range radar equipment fitted with integral antennas operating in the 24 GHz range.

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 in the 24 GHz range. It covers integrated transceivers and separate transmit/receive modules.

The present document covers only 24 GHz SRR equipment for road vehicles.
