Description
Technical Field
The utility model relates to a sensor technical field, concretely relates to radar structure.
Background
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 (> 6 m), 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 ultrasonic blind area monitoring is that the ultrasonic sensors are arranged on the left side and the right side of the tail part of a vehicle, the display screens are arranged on the rearview mirrors on the left side and the right side of the vehicle to display the blind area scene, the monitoring system is arranged to be incapable of completely covering the blind area, the installation mode is only suitable for small automobiles and is arranged on medium-large passenger and freight vehicles, and the potential safety hazard still exists when a driver drives the vehicle.
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, the currently mainstream automotive radar, 24GHz radar, is limited by frequency band control, radio astronomy 5Km does not allow the use of the band radar, and the volume of the automotive radar itself is large (mainly the antenna volume), and the like, and the automotive radars of 77GHz and 79GHz, which are gradually commercialized and equipped with some high-end automobiles, have wider distribution frequency band, higher distance resolution, relatively smaller volume, and strong target detection capability, and can be sensor devices capable of rapidly sensing information such as the distance, speed, azimuth angle and the like of peripheral environmental objects in the range of 0-200 meters in all weather scenes, so in the field of automotive automatic driving safety, automotive millimeter wave radar sensors have become one of the core components, wherein 7GHz 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.
