Abstract

The invention discloses a millimeter wave radar testing system and method for a vehicle. The system comprises a microwave darkroom, a transmitting and receiving antenna, a transmitting antenna, a radar target echo simulating device, a road electromagnetic environment simulating device and a controller, wherein the transmitting and receiving antenna and the transmitting antenna are arranged in themicrowave darkroom, the radar target echo simulating device, the road electromagnetic environment simulating device and the controller are located outside the microwave darkroom; a darkroom door is arranged on the microwave darkroom, a preset mark is arranged in a common radiation range of the transmitting and receiving antenna and the transmitting antenna, the transmitting and receiving antenna is connected with the radar target echo simulating device, and the transmitting antenna is connected with the road electromagnetic environment simulating device. According to the millimeter wave radartesting system for the vehicle disclosed by the embodiment of the invention, the accuracy and the reliability of millimeter wave radar for the vehicle during use on the actual road can be verified, and data support is provided for the design of anti-interference performance of the millimeter wave radar for the vehicle.

Description

technical field [0001] The present invention relates to the technical field of millimeter-wave radar for vehicles, and more specifically, to a testing system and method for millimeter-wave radar for vehicles. Background technique [0002] In recent years, with the rapid increase of car ownership, more and more traffic accidents caused by collisions and avoidances have seriously affected people's travel safety. In order to reduce the traffic accidents caused by collision and avoidance, all countries are working hard to study active collision avoidance technology to improve the active safety performance of automobiles. Among them, because the vehicle millimeter-wave radar can detect the target information in front of the vehicle and around the vehicle, help the driver to judge the dangerous information in advance, and has the advantages of wide coverage, small size, light weight and high positioning accuracy, it has been widely used in advanced In ADAS (Advanced Driver Assist...

AI Technical Summary

Problems solved by technology

Although the existing technology has carried out functional performance tests in the R & D and production stages of automotive millimeter-wave radars and the loading and offline stages, because the functional performance test schemes of automotive millimeter-wave radars in the prior art have not considered and carried out The functional performance test of the wave radar when it is subjected to various electromagnetic interferences on the actual road, so it cannot verify the accuracy and reliability of the millimeter-wave radar for vehicles when used on the actual road

In addition, if the functional performance of the existing millimeter-wave radar for vehicles does not meet the requirements under one or several kinds of electromagnetic interference, the functional performance test plan of the millimeter-wave radar for vehicles in the prior art cannot find Under what kind of electromagnetic interference, the functional performance does not meet the requirements, and it cannot provide data support for the design of the anti-interference performance of the automotive millimeter-wave radar.
