一种便携式机载雷达罩外场电性能测试系统

A Portable External Field Electric Performance Test System for Airborne Radome

摘要:

雷达罩在使用过程中可能会出现进水、蒙皮脱落、蒙皮穿孔等损伤,这些损伤会影响着雷达罩的电性能。针对外场条件下对机载雷达罩电性能测试需求,设计了一种便携式、易操作的雷达罩电性能测试系统。给出了透波率、插入相移、介质常数等雷达罩电性能参数测试方案,并对雷达罩样品的电性能参数进行了测试,结果表明：该系统在外场条件下能够方便的测量雷达罩电性能参数,测试结果真实有效。

Abstract:

In the use of radome, it may cause damage to cover body, skin shedding and skin perforation, which will affect the electrical performance of radome. Aiming at the requirement of electric performance test for airborne radome under external conditions, a portable and convenient radar performance test system is designed. The testing scheme of the radar cover electrical performance parameters, such as the penetration rate, the insertion phase shift and the medium constant, is given, the electrical performance parameters of radome samples were tested. Test results show that: the system can conveniently measure the electrical performance parameters of radome under external conditions, and the test results are real and effective.
