Introduction Automotive and surveillance radar equipments are low power millimetre wave devices that are able to detect and characterize
34、 targets in their environment. The following use cases are included (but are not limited to): automotive Advanced Driver Assistance Systems (ADAS) applications, such as Adaptive Cruise Control (ACC), Blind Spot Detection (BSD), parking aid, backup aid, autonomous braking and Pre-Crash Systems (PCS);
35、 surveillance radars for other kind of ground based vehicles, such as trains, trams, aircrafts while taxiing; fixed infrastructure radars for traffic monitoring; railway/road crossings obstacle detection radars; ETSI ETSI EN 303 396 V1.1.1 (2016-12) 7 helicopter obstacle detection radars. Detailed i
36、nformation about use cases can be found in the related Harmonised Standards (ETSI EN 301 091-1 i.7, ETSI EN 301 091-2 i.8, ETSI EN 301 091-3 i.9, ETSI EN 302 264 i.10, ETSI EN 302 858 i.11). The current generation of radars uses mainly FMCW modulations, such as slow-ramp and fast-ramp (chirp or puls
37、e compression) modulations. Radars may have multiple transmitting antennas and receiving antennas to enable adaptive field-of-views or digital beam forming. Scanning systems, electronically or mechanically, also exist on the market. ETSI ETSI EN 303 396 V1.1.1 (2016-12) 8 1 Scope The present documen
38、t describes possible measurement techniques and procedures for the conformance measurements applicable to automotive and surveillance radar equipments. The present document will be used as a reference for existing and future ETSI standards covering automotive and surveillance radar equipments. 2 Ref
