Abstract

The present invention provides a radar performance monitoring method, device and storage medium, wherein the method includes: determining the measured distance value and signal-to-noise ratio corresponding to each target point according to the echo signal of the current frame, and based on all the measured distances value and signal-to-noise ratio to estimate the fusion inferred distance corresponding to the current frame, wherein the fusion inferred distance indicates the estimated maximum detection distance of the radar; filter the fusion inferred distance corresponding to the current frame to obtain the current frame Corresponding decision decision value; comparing the decision decision value corresponding to the current frame with at least one preset threshold to determine the current working state of the radar. The technical solution provided by the embodiment of the present invention can realize real-time self-detection of radar occlusion performance and determine the current working state of the radar, and the method has strong robustness and can respond to the degradation of radar performance caused by bad weather or environmental factors , which effectively ensures the perception ability of the vehicle radar to the environment.

Description

technical field

[0001] The invention relates to the technical field of vehicle-mounted radar, and in particular to a radar performance monitoring method, device and storage medium. Background technique

[0002] Automotive radar is very important to improve the driving safety performance of automobiles. Among them, the millimeter-wave radar in automotive radar has the advantages of high range resolution, low radiation power, and small size, so it is widely used in advanced driver assistance systems and automatic driving. The basic working principle of millimeter-wave radar is to obtain the relative distance and speed of the measured target by continuously and periodically modulating the frequency of the transmitted signal and analyzing the frequency of the signal at the time of transmission and reception.

[0003] Existing radar performance monitoring methods mainly refer to occlusion detection, that is, to determine whether the current radar has physical occlusion through v...
