Abstract

The invention relates to an automatic test system and method of a vehicle millimeter wave radar simulation scene. The automatic test system of the vehicle millimeter wave radar simulation scene includes a test control computer, vehicles and scene simulation tools, a radar target simulator and radar to be tested; and a control system is arranged in the test control computer. The test method performed by using the automatic test system of the vehicle millimeter wave radar simulation scene comprises the following steps: combining the vehicles and scene simulation tools and the system, and using the vehicles and scene simulation tools to perform simulation and construction on vehicle types, road environments, weather conditions and the like; using the target simulator and the radar to be tested to perform transmission and reception on target information; and using the control system to perform real-time collection and saving on the target information, perform comparison, judgment, analysisand process with the working condition scene information constructed by the simulation tools, and automatically output a detection report. The invention integrates the vehicles and scene simulation tools and the system to form a complete, effective and integrated millimeter wave radar automatic test system.

Description

technical field [0001] The invention relates to the technical field of radar, in particular to an automatic test system and method for a vehicle-mounted millimeter-wave radar. Background technique [0002] As the main sensor in the advanced driver assistance system or automatic driving system, the vehicle-mounted millimeter-wave radar is gradually used in passive safety and active safety systems. The driver perceives possible dangers in the shortest time to attract attention and improve safety, and avoid or reduce traffic accidents through prior prevention. [0003] At present, the scene tests of vehicle-mounted millimeter-wave radar products developed are mostly carried out through traditional site tests and real vehicle road tests, which is not only costly, time-consuming, and uncontrollable conditions; Snow, summer and winter, etc.) cannot be tested and verified. As a result, the radar product cannot be fully tested and verified in a short period of time, and the projec...
