暗室用吸波材料大入射角吸波特性测试方法研究

Study of Testing Methods for Absorption of RAM Usedin Chamber with Large Incident Angle

摘要: 本文介绍了根据对比原理测试吸波材料性能的一种方法，把通常采用的弓形法和RCS法进行了对比，指出弓形法在大入射角度情况下测试存在的困难，而在大的微波暗室内可以较好地解决大入射角测试的问题，最后给出了一组在RCS暗室内进行材料测试的结果，并对测试结果进行了分析。

Abstract: A method of RAM absorption testing based on comparison principle is described. The difference between NRL-arc method and RCS method is given. It is difficult to perform test in large incident angle using NRL-arc method. While using RCS method in large chamber, it is easier. At last, a set of testing results with analysis are presented.
