Abstract

The invention discloses a radar anti-same-frequency-interference method and device. The radar anti-same-frequency-interference method comprises the steps that step 1, a filtering circuit decreases thepower difference between a high frequency part and a low frequency part in a baseband signal and filters a baseband out-of-band signal in the baseband signal; step 2, a signal processing unit automatically adjusts the amplification gain of an automatic gain amplification circuit according to an echo signal received by a receiving antenna; step 3, the signal processing unit changes the frequency of a radio-frequency signal generated by a signal generating unit randomly; and step 4, the signal processing unit filters a same-frequency interference signal through a target tracking method. The problem of same-frequency interference between radars is solved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of automobile safety control, in particular to a radar anti-same-frequency interference method and device. Background technique [0002] With the improvement of people's living standards and the development and progress of science and technology, automobiles have become a means of transportation for everyone to travel, which brings convenience to people and also brings certain hidden dangers. In recent years, radar products based on millimeter-wave technology have become a standard accessory for many cars as part of car driver assistance systems. Compared with video systems, automotive millimeter-wave radar is not affected by external conditions such as weather, temperature, and humidity. It has been applied and developed in many aspects of vehicles, such as adaptive cruise control (ACC), automatic emergency braking system (AEB ), Blind Spot Detection System (BSD), Access Assist System...
