scope:

The present document specifies the technical requirements and methods of measurement for Short Range Devices (SRD) working as broadband devices with at least 50 MHz occupied bandwidth in the 77 GHz to 81 GHz frequency range, hereinafter referred to as the 79 GHz range, intended for Road Transport and Traffic Telematics (RTTT) applications. Applications include e.g. Short Range Radar (SRR) for obstacle detection, stop&go, blind spot detection, parking aid, backup aid, precrash and other automotive applications. Applications that might interfere with automotive SRR systems, e.g. road infrastructure systems, are explicitly excluded.

The present document covers transmitters intended to operate in the frequency range as defined in the EC decision 2004/545/EC [i.2] and the ECC decision ECC/DEC/(04)03 [i.1].

The document applies to:

a) transmitters in the 79 GHz range operating as broadband devices;

b) receivers operating in the 79 GHz range;

c) integrated transceivers in the 79 GHz range.

The present document:

• contains the technical characteristics and test methods for short range radar equipment fitted with integral antennas operating in the 79 GHz range;

• covers short range radar vehicle applications in the 79 GHz range. It covers integrated transceivers and separate transmit/receive modules.

The present document is intended to cover the provisions of Article 3.2 of Directive 1999/5/EC [i.3] (R&TTE Directive), which states that "... radio equipment shall be so constructed that it effectively uses the spectrum allocated to terrestrial/space radio communications and orbital resources so as to avoid harmful interference".
