DANSK DS/EN 303 360 V1.1.1 [ Active ]

The present document applies to radar equipment for obstacle detection for rotorcraft use in the frequency range from 76 GHz to 77 GHz. It covers integrated transceivers. The present document specifies the requirements for Short Range Devices (SRD) intended for the use on board rotorcrafts with the application to detect obstacles. NOTE 1: The intention of the application is to detect obstacles to increase safety for aircrew, passengers and persons on ground by reducing risk of collision with obstacles. It is not considered as a safety of life application. NOTE 2: Protection to the Radio Astronomy Service as detailed in Annex B is applicable for obstacle detection radars for rotorcraft use as described in the present document. The present document contains the technical characteristics and test methods for obstacle detection for rotorcraft use radar equipment fitted with integral antennas operating in the frequency range from 76 GHz to 77 GHz and references CEPT/ERC/ECC Recommendation 70-03 [i.1], Annex 5 and Commission Decision 2006/771/EC [i.2] as amended. In case of differences (for instance concerning special conditions, definitions, abbreviations) between the present document and ETSI EN 303 396 [1], the provisions of the present document take precedence. 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.
