摘　　要：为了高效、安全地对汽车自动辅助驾驶系统进行验证,文中提出一种基于距离欺骗原理的对其车载防撞雷达性能的试验方法。安装有矢量信号分析软件的实时频谱分析仪对被测车辆的雷达发射信号进行分析,然后采用电子系统仿真建模软件SystemVue编辑生成雷达回波信号波形文件,将其导入微波信号发生器中产生雷达回波模拟中频信号,经后续处理产生具有虚假距离信息的回波模拟射频信号。试验结果可知:即使不存在障碍物,被测车辆雷达收到回波模拟信号后,也能立即停车避险,且截停概率可达99%以上,提高了汽车自动辅助驾驶系统测试的效率与安全性。In order to test and verify automobile auto-assisted drive system efficiently and safely,a new test method based on range deception is proposed. Firstly,signal transmitted by radar on the vehicle-under-test is analyzed by using real-time spectrum analyzer（ vector signal analyzing software is installed）; then edit and generate radar echo signal waveform file by using an electronic system modeling and simulation software SystemVue; load the file to a microwave signal generator to generate radar echo analog IF signals; and generate echo analog RF signals with false range information through succeeding processing. Test results show that,the vehicle-under-test will stop to prevent collision immediately even there is no obstacle,probability of car stopping is above 90%; which can improve test efficiency and safety of auto-assisted drive system significantly.
