The present document applies to radar equipment for obstacle detection applications in the frequency range from
76 GHz to 77 GHz at the road crossing of a railway track. It covers integrated transceivers and separate transmit/receive
Also the present document specifies the requirements for Short Range Devices (SRD) intended for the use at road
crossing of a railway track.
The present document applies to:
• equipment with an integral antenna;
• fixed devices;
• operating in the frequency range from 76 GHz to 77 GHz.
The present document contains the technical characteristics and test methods for obstacle detection radar equipment
fitted with integral antennas operating in the frequency range from 76 GHz to 77 GHz and references CEPT/ECC ERC
Recommendation 70-03 [i.1] Annex 4.
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.
These radio equipment types are capable of operating in all or part of the frequency bands given in table 1.
Table 1: Permitted range of operation [i.1]
Permitted range of operation
Transmit 76 to 77 GHz
Receive 76 to 77 GHz
The present document contains requirements to demonstrate that radio equipment both effectively uses and supports the
efficient use of radio spectrum in order to avoid harmful interference.
