The Ministry of Industry and Information Technology has authorized the experiment in four cities to carry out technical solution verification and frequency test.
As a major automobile production and sales country, the Chinese government has long paid great attention to the technological and industrial changes brought about by the intelligentization of automobiles, and has given various support to emerging technology products at various levels such as policies, plans and standards. In 2016, the Chinese government officially launched the ITU Global Transport Unified Frequency (WRC-19 1.12) issue. As an important component of smart cars and smart transportation, the frequency division of the vehicle's millimeter-wave radar is also closely watched by the Chinese government. A highly regarded technical field.
According to WRC-19 1.12, the lead agency of the China proposal: Pang Chunlin, secretary general of the In-vehicle Information Service Industry Application Alliance (referred to as: Automobile Association), in order to better carry out the above work, on the basis of the preliminary work, the Ministry of Industry and Information Technology issued the issue Regarding the approval of the In-vehicle Information Service Industry Application Alliance to carry out the research on the frequency research and test of intelligent transportation radio technology (the Ministry of Industry and Information Technology has no letter [2016] No. 450) document, authorize the car unit to organize industrial units in Hefei City, Anhui Province, Dalian City, Liaoning Province, Jiangsu Province Taizhou City, Mianyang City, Sichuan Province carried out research and test of 77-81GHz vehicle millimeter wave radar, conducted wireless technology solution verification and frequency test, verified radar performance parameters, frequency requirements, RF parameters, radiation power, electromagnetic compatibility and other technologies. The index provides technical reference for China's vehicle ranging radar frequency planning and WRC-19 1.12 issue China proposal, and promotes the use of vehicle ranging radar in China's smart car and smart transportation industry with high efficiency, security, safety and reliability. Radar materials, components, systems and machine industry development.
With the development of intelligent vehicles, the millimeter-wave radar for vehicles has long detection distance, long bandwidth, small antenna, high integration, stable detection performance, no influence on the surface shape and color of the detected object, and is not affected by large airflow. Advantages, as well as good environmental adaptability, have become an indispensable equipment in car collision warning, adaptive cruise, active safety (ADAS) and even automatic driving technology. According to relevant statistics, in 2014, the global automotive millimeter wave radar market shipments were 19 million, and it is expected to reach 72 million by 2020. The compound growth rate in the next five years is about 24%, and the total market will exceed 20 billion. yuan.
