如何准确测试一个飞机上单独部件自身的雷达散射截面(RCS)特性,是隐身性能研究的一个重要方面。文中以飞机上的某一部件为例,分析了该部件RCS测试的影响因素,针对部件开放端口不连续引起的散射问题提出了RCS测试用载体的设计原则和方法,利用多层快速多极子方法对载体进行设计仿真和优化,从而有效保证RCS测试数据的准确性。

How to exactly test radar cross section (RCS) of one component of fighter plane itself is an important part of stealth design. Taking one component of aircraft for example,this paper analysed the factors that infulence the RCS test and in an aim to solve the scattering caused by open edge discontinuity, the design criteria and methodologies for the RCS test is studied and put forward. Further, Multi-layer fast multi-pole methods are used to conduct simulation and optimization for the design of carrier to guarantee the accuracy of test data obtained from RCS test.
