From time to time we see news about traffic accidents, and most of these accidents are related to large trucks, so that large trucks become "road killers" in many people's eyes. Most accidents of large trucks are related to 'blind areas', because the bodies of medium and large trucks are generally longer (>6m), the current domestic buses and buses are 12 m larger, the trucks are classified into various types according to application ranges and functions, and the longest vehicle is 17 m. Because the length of the body of the medium and large-sized passenger and freight vehicles is longer, when a driver turns or changes lanes when driving the vehicles, a blind area exists on the side surface of the body, the driver can hardly see the situation of coming vehicles of the blind area on the side surface indoors, accurate judgment can not be made, and traffic accidents are easy to happen.
In view of this phenomenon, there are several main preventive measures in the market: video blind area monitoring, ultrasonic blind area monitoring and the like. The video blind area monitoring is realized by installing cameras at the positions of the left side rearview mirror and the right side rearview mirror of the vehicle to acquire video data. However, the installation mode of the monitoring system is not beautiful, and when the vehicle runs in rainy and snowy days or at night, the monitoring system is influenced by weather conditions, the monitoring quality is reduced, and drivers cannot clearly see blind area scenes in the cab, so that the probability of traffic accidents is greatly improved.

The radar sensor is arranged on the automobile, so that the functions of collision prevention, automatic parking, pedestrian detection and the like of the automobile are realized, the automobile gradually walks out of the automobile auxiliary intelligent driving system, and the automobile auxiliary intelligent driving system represents a trend of realizing unmanned driving in the future. However, because the current mainstream automobile radar, namely the 24GHz radar, is limited by frequency band control, the radio astronomy 5Km does not allow the use of the band radar, the size of the radar is large (mainly the antenna size), and the like, and the automobile radars are gradually commercialized and equipped with 77GHz and 79GHz which have wider distribution frequency bands, higher distance resolution, relatively smaller size and strong target detection capability, and can be sensing devices capable of rapidly sensing information such as the distance, the speed, the azimuth angle and the like of peripheral environment objects in the range of 0-200 meters in all weather scenes, the automobile millimeter wave radar sensor has become one of the core components in the field of automobile automatic driving safety, wherein the 77GHz and 79GHz millimeter wave radars are essential key components on intelligent automobiles. However, the volume of the radar does not allow the installation of components exceeding 32mm on the side bodies of medium and large passenger trucks, particularly large passenger trucks, so that the application of the 7GHz and 79GHz automobile radar on the medium and large passenger trucks is limited to a great extent.
