scope:

The present document specifies the technical requirements and methods of measurement for Short Range Devices (SRD) working as UWBdevices 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 [i.7], the EU Commission decision on 24 GHz SRR 2005/50/EC [i.1] and the amendment as presented in RSCOM11-07 21 [i.8].

The operating frequency range for intentional UWB emissions with at least 500 MHz bandwidth in the 22,000 GHz to 26,65 GHz range until 30^th June 2013 as given in annex D and from 24,25 GHz to 26,65 GHz until 1st January 2018 as given in annex E. However, the date of 1 January 2018 will be extended by 4 years for automotive short-range radar equipment mounted on motor vehicles for which a type approval application has been submitted pursuant to Article 6(6) of Directive 2007/46/EC [6] and has been granted before 1 January 2018.

The present document applies to:

a) Transmitters in the range from 22,000 GHz to 26,65 GHz operating as UWB 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 [i.2] and the methods for compliance demonstration in EN 50371 [i.3].
