ETSI EN 301 091-1

ETSI EN 301 091-1 specifies the requirements for Short Range Devices (SRD) intended for Road Transport and Traffic Telematics (RTTT) applications such as Automotive Cruise Control (ACC), Collision Warning (CW), Anti-Collision (AC) systems, obstacle detection, Stop and Go, blind spot detection, parking aid, backup aid and other automotive applications.

The document applies to:

a) transmitters operating in the range from 76 GHz to 77 GHz;
b) receivers operating in the range from 76 GHz to 77 GHz.

The present document contains the technical characteristics and test methods for automotive radar equipment fitted with integral antennas operating in the frequency range from 76 GHz to 77 GHz and references CEPT/ERC/ECC Recommendation for SRDs, CEPT/ERC/ECC Recommendation 70-03 [1] and CEPT/ECC Decision (02)01 [2].

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 automotive radars for mobile applications in the frequency range from 76 GHz to 77 GHz. It covers integrated transceivers and separate transmit/receive modules.

The present document covers only equipment for road vehicles.

There are two classes defined within the present document: Class 1 (e.g. FM, CW or FSK) and Class 2 (pulsed Doppler radar only). The difference between the two class numbers is the permitted average power level.
