Abstract

The invention is suitable for the technical field of radar and provides an interference suppression method for a radar and terminal equipment. The method comprises the steps: obtaining the sampling data of a first receiving channel, wherein the first receiving channel is any one of the receiving channels of the radar; determining a first data sequence and a second data sequence according to the sampling data of the first receiving channel; determining a first threshold value and a second threshold value according to the first data sequence and the second data sequence; determining abnormal data in the sampling data of the first receiving channel according to the first data sequence, the second data sequence, a first threshold value and a second threshold value; and processing abnormal datain the sampling data of the first receiving channel to obtain processed sampling data of the first receiving channel. By adopting the method, abnormal data in the sampling data of the receiving channels of the radar can be effectively eliminated, cross interference is suppressed, and the target identification accuracy of the radar is improved.

Description

technical field [0001] The invention belongs to the technical field of radar, and in particular relates to a radar interference suppression method and terminal equipment. Background technique [0002] With the vigorous development of the automobile industry, in order to reduce traffic accidents, improve road traffic safety and enhance road traffic capacity, vehicle radar has been widely used. The vehicle-mounted radar emits electromagnetic waves and receives the echoes, and obtains information such as the distance and relative speed of the target according to the delay and frequency changes between the echoes and the emitted waves. However, when multiple radars are used simultaneously on the same occasion, multiple radars There will be mutual interference between them, which will reduce the accuracy of radar target recognition. Therefore, the mutual interference between radars needs to be considered in the design of the radar to eliminate the resulting false target identifi...
