传输损耗是天线罩的重要性能指标之一。简述了Ka波段某动中通天线罩的基本特性。介绍了远场法测量天线罩传输损耗的原理方法。对天线罩测量误差进行了分析,结果表明其总均方根误差≤0.116d B,最后给出了Ka波段某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。
Transmission loss is one of the important performance indicators radome. The basic characteristics of a moving radome in Ka band are briefly described. The principle and method of measuring the radome transmission loss by far-field method are introduced. The measurement error of the radome is analyzed. The result shows that the total root mean square error is less than or equal to 0.116d B. Finally, the measurement results of the insertion loss of the radome in a certain band in Ka band are given. The measured results are in good agreement with the theoretic budget.
