利用同步卫星测量天线远场增益技术分析

内容简介：为解决非理想远场条件下卫星导航系统天线增益测量的问题，提出了一种基于波束宽度法利用同步导航卫星测蜒低仰角抛物面天线实际远场增益的方法。依托于工程应用，完成了抛物面天线的远场增益的实地测量，消除了反射、遮挡误差，并同，一家利用积分法在理想外场的测试数据进行列比对分析，通过工程验证，体现了该种方法的正确性。

Abstract：In this paper,based on the method of measuring beam width,a new method is proposed,using geostationary navigation satellite to measure the real far-field gain of low elevation paraboloid antenna. Relying on the engineering application, the road-test of far-filed gain of paraboloid antenna is completed,which eliminates the reflecting and sheltering errors. And the contrast analysis is im- plemented with the test data acquired by the antenna manufacturer using the integral method in ideal outfield. Through engineering veri- fication, the validity of the proposed method is represented.
