ETSI EN 302 858-1 specifies the technical requirements and methods of measurement for automotive radar equipment operating in the 24,05 GHz to 24,25 GHz frequency range or in the 24,05 GHz to 24,50 GHz frequency range intended for Narrow Band Short Range Radar (NB SRR) for Road Transport and Traffic Telematics (RTTT) applications such as Automotive Cruise Control (ACC), Collision Warning, Anti-Collision (AC) systems, obstacle detection, Stop and Go, blind spot detection, parking aid, precrash, backup aid and other safety relevant automotive applications.

The present document contains the technical characteristics and test methods for narrowband short range radar equipment fitted with integral antennas and applies to transmitters and receivers with integral antennas operating in all or part of the range from 24,05 GHz to 24,50 GHz.

The present document covers the basic NB SRR as provided by the EN 302 858-1 (V1.2.1) operating in the frequency range of 24,05 GHz to 24,25 GHz.

Additionally, the present document specifies the WLAM (Wideband Low Activity Mode) mode, operating from 24,05 GHz to 24,50 GHz. The operation of this mode is optional and specified in the normative annex B of the present document.

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 only NB SRR equipment for vehicles.

The present document complies with field limits for human exposure to electromagnetic fields as provided by the EC Recommendation 1999/519/EC [i.4] and the methods for compliance demonstration in EN 62479:2010 [i.5].
