基于矢量网络分析仪的宽带步进频RCS测试系统

Broadband stepped frequency RCS test system based on VNA

介绍了雷达散射截面测试的基本原理,并提出了一种基于矢量网络分析仪的宽带步进频雷达散射截面积(RCS)测试方法。在微波暗室中,使用24GHz频段对实车毫米波雷达道路测试所用的模拟障碍物及真实障碍物进行了RCS测试,通过测试结果验证了模拟障碍物的准确性。

This paper introduces the basic principle of RCS measurement, a broad band and stepped frequency RCS test system based on VNA is presented. In the anechoic chamber, RCS test is carried out on the simulated obstacles and real obstacles used in the millimeter-wave radar road test in the 24 GHz band. the accuracy of the simulated obstacles is verified by the test results.
