The invention relates to a microwave camera obscura for an automobile high-frequency radar test. The camera obscura comprises a camera obscura body, a radar to be tested is arranged in the camera obscura body, a fixed bracket is arranged in the camera obscura body, and the radar to be tested is arranged at the top of the fixed bracket; at least two arc tracks are further arranged in the camera obscura body, each arc track is connected with an antenna support in a sliding mode, and an antenna is installed at the top of each antenna support; and the antenna support is also provided with a driving mechanism, and the driving mechanism is used for driving the antenna support to slide along the corresponding arc track. According to the invention, the at least two arc tracks are arranged, each arc track is slidably connected with the antenna support, the antenna can be set and accurately moved according to a test scene, a test angle can be set, and at least two antennas are arranged so that at least two interference sources can be simulated, the scene is closer to a real scene, and the test precision of the radar can be improved.
Description
technical field [0001] The invention relates to the technical field of microwave dark boxes, in particular to a microwave dark box used for automotive high-frequency radar testing. Background technique [0002] As the main means of transportation in modern society, cars are making great strides in the direction of intelligence and networking, and the assisted driving system is an important guarantee for the safety of smart cars. Millimeter wave radar is one of the main sensors in the assisted driving system , therefore, the function test of the radar is particularly important. [0003] When testing the performance of automotive radar, a large number of test scenarios are required, and the cost of on-site testing is high. Therefore, those skilled in the art propose to simulate the target motion scene in the microwave obscura to realize the sensor simulation test of the Advanced Driver Assistance System (ADAS). [0004] Chinese invention patent CN201710330502.4 discloses a ve...
