AI Technical Summary

Problems solved by technology

It is difficult and costly to build a microwave anechoic chamber for millimeter-wave radar testing, and the complex test environment will lead to invalid test results
At present, millimeter-wave radar manufacturers mainly build or rent microwave anechoic chambers for system testing. The absorbing materials required to build high-frequency microwave anechoic chambers are expensive, and building a microwave anechoic chamber often requires tens of millions or even hundreds of millions of funds. The requirements for the design of the anechoic chamber are very high, otherwise the microwave absorption effect will be extremely poor, and the rental microwave anechoic chamber test will take a long time, which is not conducive to repeated tests
[0003] Therefore, there are problems in the prior art that the test environment for radar performance testing is expensive, cannot meet the requirements of the test, is not conducive to multiple tests, and has low reliability of test results.

Abstract

A test method (100) and system (200) for radar (210) performance are disclosed. The method (100) includes: calibrating the radar (210), the radar (210) being installed outdoors (S110), and controllingthe radar (210) to face a corner reflector (220), wherein the corner reflector (220) is disposed on a drone (230) (S120); acquiring the transmission and reception test signal data of the radar (210)to obtain the performance data of the radar (210) (S130). The radar (210) performance test method (100) and system (200), avoid the costly construction of a complex microwave darkroom environment, andgreatly reduce the radar (210) test cost and test difficulty, and the test results are highly reliable.

Description

technical field [0001] The invention relates to the technical field of radar, in particular to a method and system for testing radar performance. Background technique [0002] In recent years, the field of autonomous driving has developed rapidly, and millimeter-wave radar as an important sensor has also developed rapidly. At present, the millimeter-wave radar mainly uses the 77GHz frequency band, and the higher frequency band brings certain difficulties to the test. It is difficult and costly to build a microwave anechoic chamber for millimeter-wave radar testing, and the complex test environment will lead to invalid test results. At present, millimeter-wave radar manufacturers mainly build or rent microwave anechoic chambers for system testing. The absorbing materials required to build high-frequency microwave anechoic chambers are expensive, and building a microwave anechoic chamber often requires tens of millions or even hundreds of millions of funds. The requirements ...
