Radar anti-ground clutter improvement factor test method based on body acoustic wave microwave delay line

提出了一种基于声体波微波延迟线和上下变频技术模拟固定地物回波信号的雷达抗地杂波改善因子测试方法,以其设计并制作了用于雷达抗地杂波改善因子测试的目标模拟器。给出了传统抗地杂波改善因子测试方法和目标模拟器测试方法在两个典型雷达上进行的静、动态抗地杂波改善因子对比测试实例。结果表明使用目标模拟器的测试方法可以满足测试精度要求,且与传统测试方法相比,具有适用范围广,对测试场地、设备要求低,操作简便等优点。

A radar system anti-ground clutter improvement factor test method based on body acoustic wave microwave delay line and frequency conversion technology simulating fixation clutter was presented, and a target simulator was designed and fabricated by using this method. Static and dynamic anti-ground clutter improvement factor comparison tests were given by traditional test way and target simulator method in two typical radars. Results show that the test method by using the target semulator can meet accuracy requirement. Comparing with the traditional test way, it has advantages such as wide scope, low requirement of test site and equipment, and easy operation.
