Abstract

The invention discloses a target object detection method and a corresponding detection device, relates to the field of wireless communication, and can solve problems of low target object detection result accuracy and the like caused by mutual interference between radar detection devices in the prior art. The method is characterized in that each detection device transmits a radio signal in the determined frequency band capable of avoiding mutual interference so that interference of the transmitted signal or a related signal of any detection device on the target object determined by other detection devices is avoided. Furthermore, the frequency band is divided according to the determined threshold value, the frequency bands are allowed to be partially overlapped, frequency resources can be effectively utilized, frequency domain resource waste caused by complete separation of the sweep frequency bands of the multiple detection devices in the frequency domain is avoided, high anti-interference performance is achieved with low frequency resource cost, and in addition, radar communication of more purposes can be supported. The method is advantaged in that the ADAS capability of an automatic driving or advanced driving assistance system of the automobile is improved, and the method can be applied to the Internet of Vehicles, such as vehicle external V2X, inter-vehicle communication long-term evolution technology LTE-V, vehicle-vehicle V2V and the like.

Description

technical field [0001] The embodiments of the present application relate to the field of wireless communication, and in particular, to a method for detecting a target by using radio and a corresponding detection device. Background technique [0002] With the development of society, more and more machines in modern life are developing toward automation and intelligence, and cars for mobile travel are no exception. Smart cars are gradually entering people's daily lives. In recent years, the Advanced Driving Assistant System (ADAS) has played a very important role in smart cars. The system uses various sensors installed on the car to sense the surrounding environment while the car is driving. , Collect data, carry out identification, detection and tracking of stationary and moving objects, and combine the map data of the navigator to carry out systematic calculation and analysis, so as to let the driver perceive possible dangers in advance and effectively increase the comfort o...
