Problems solved by technology

[0006] 2. It is difficult to achieve quantitative repeatability testing
[0007] 3. The test efficiency of the road test for the scene is low
When building a multi-target and multi-object scene, regardless of the test site or road test, building the scene requires a lot of preparation and coordination work, which is difficult to achieve for fatigue tests that require multiple repetitions

Abstract

The invention discloses a radar function testing system and a testing method. The testing system comprises an upper computer, a radar echo simulator, and a power simulation system. The upper computeris used for operating a scene simulation software to build a target model and a vehicle model. The radar echo simulator is used for simulating the waveform of a target according to characteristic information of the target and sending the waveform of the target to a to-be-tested radar. When the to-be-tested radar receives the waveform of the target, a decision control signal used for controlling action of the vehicle model is fed back to the power simulation system, and function characteristics of the to-be-tested radar are tested based on the decision control signal. According to the radar function testing system and the testing method, multidirectional multi-target scene simulation is achieved, and stability of target simulation is improved.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a radar function test system and a test method thereof. Background technique [0002] Road safety has become a global challenge faced by the road traffic system. Due to the continuous improvement of automobile safety standards in various countries, the active safety technology Advanced Driver Assistance System (ADAS) has shown a rapid development trend in recent years. [0003] For target recognition technology, the working principle is different, mainly based on ultrasonic, laser, image, millimeter wave and other methods. Based on the comprehensive consideration of cost, reliability under harsh environmental conditions, and target recognition performance, automotive millimeter-wave radar has become a key factor driving this field. [0004] At present, there are many ways to realize millimeter-wave-based vehicle radio technology, and related modules have been applied in act...
