DANSK DS/EN 301 489-51 V1.1.1 PDF

The present document, together with ETSI EN 301 489-1 [1], covers the assessment of automotive, ground based vehicles and surveillance radar devices using 24,05 GHz to 24,25 GHz, 24,05 GHz to 24,5 GHz, 76 GHz to 77 GHz and 77 GHz to 81 GHz in respect of ElectroMagnetic Compatibility (EMC). Technical specifications related to the antenna port and emissions from the enclosure port of radar equipment are not included in the present document. Such technical specifications are found in the relevant product standards for the effective use of the radio spectrum. The present document specifies the applicable test conditions, performance assessment and performance criteria for automotive and surveillance radar devices and associated ancillary equipment. Automotive and surveillance radar equipments are low power millimetre wave devices that are able to detect and characterize 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); • 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; • helicopter obstacle detection radars. Examples of automotive and surveillance radar devices are given in the related harmonised standards. In case of differences (for instance concerning special conditions, definitions, abbreviations) between the present document and ETSI EN 301 489-1 [1], the provisions of the present document take precedence. The environmental classification and the emission and immunity requirements used in the present document are as stated in ETSI EN 301 489-1 [1], except for any special conditions included in the present document.
