摘　　要：插入损耗是天线罩的重要性能指标之一。简述了Ku波段0.9 m动中通天线罩的基本特性。介绍了远场法测量天线罩插入损耗的原理方法。提出了转动天线罩方位,抬高座架以改变天线夹板角,实现天线罩插入损耗均匀性测量。最后给出了Ku波段0.9 m动中通天线罩插入损耗测量结果,测量结果同理论预算基本吻合。Insertion loss is one of the important performance indexes of the radome. The basic characteristics of Ku-band0.9 m radome for satellite communication in motion（SCM） are described briefly. The principle and method that the far field method is used to measure the radome insertion loss are introduced. By means of turning the radome azimuth and raising the seat frame to change the angle of antenna splint,the uniformity measurement of the radome insertion loss is realized. The measurement results of insertion loss for Ku-band 0.9 m radome for SCM are given,which are basically identical with the theory computing results.
