According to the official website of the Ministry of Industry and Information Technology of China, on December 6, the ministry released the “Interim Provisions on Radio Management of Automotive Radar” (hereinafter referred to as the “Provisions”).
The main contents of this “Provisions” are as follows:
-
Except as otherwise provided by the national radio management agency, the 76-79 GHz band cannot be used for other types of land-based radar or for radar used on aircraft (including drones, balloons, airships, etc.).
-
Radio stations used for automotive radar in the 76-79 GHz frequency band do not need to apply for a radio station license, but manufacturers or importers of automotive radar equipment sold and used domestically should apply to the national radio management agency for model approval of radio transmitting equipment.
-
No harmful interference shall be caused to wireless radio services or radio stations (sites) lawfully operated in the same or adjacent frequency bands, including fixed, mobile, satellite fixed, amateur and radio astronomy, and interference protection distances between different radio astronomy station locations and automotive radar are specified in the provisions.
The “Provisions” refer to millimeter-wave radar for automobile use. As part of the car, millimeter-wave radar provides assistance for intelligent driving features of the car, mainly used for adaptive cruise control, collision avoidance, blind spot detection, lane change assistance, parking assistance, rear warning of vehicle approach, and pedestrian detection. Millimeter-wave radar has the advantage of stable target detection under adverse weather conditions such as rain and snow.
According to the Ministry of Industry and Information Technology, with the accelerated evolution of automobile electrification, networking, and intelligent technologies, the application of advanced driver assistance systems (ADAS) is becoming increasingly widespread. Millimeter-wave radar, as an important component of assisted driving functions, is increasingly standard equipment in more and more models of cars. However, radio frequencies are a resource that automotive radar relies heavily on, and it is necessary to regulate and guide its use to reduce interference between automotive radar and other wireless radio services. In order to improve relevant management regulations, the Ministry of Industry and Information Technology has issued these provisions.
