摘　　要：介绍了雷达天线罩的功能、特点及电性能要求,论述了雷达天线罩透波性能对天线辐射的影响。在专门的无外界电磁干扰的微波暗室环境中,利用Agilent8530A天线测量系统平台,自行设计了一种简单可靠的测试方法。并结合某型无人机的雷达天线罩进行了实际测试研究,测量精度误差小于0.1 dB。在不同的状态下反复试验得出涂层对透波率的影响,为新型涂层材料的研究提供了精确的实验数据。The functions,characteristics and electrical performances of the radome are presented, the ef- fects of the radome transmission performance on the antenna radiation are discussed. In the microwave dark room without outside electromagnetism interference, a simple and credible testing method is designed with a Agilent8530A antenna testing system. By testing and researching certain unmanned aircraft, the testing error is less than 0.1dB. The coating effect is acquired by many tests in different states, thus it offeres precise testing data for new coating material research.
