| 摘 要： | 为提高进近着陆系统对不断变化场地环境的适应能力,要求对着陆系统电磁环境进行准确评估.提出利用MoM和GTD算法结合的方法分析进近着陆系统电磁环境效应.用MoM计算照射到位于近区场的散射体的入射场,然后将此结果作为GTD算法的源以预测评估对着陆系统辐射场的受扰特性.结果表明这种方法可有效用于评估着陆系统电磁环境.

| Abstract: | To improve the adaptability to the increasingly changeful field environment,the landing system should known the accurate electromagnetic environment effect.Therefore,the electromagnetic environment should be correctly evaluated before the landing.A method which combined MoM and GTD algorithms on the Evaluation of Electromagnetic Environment for the Approaching Landing System was proposed in this paper.The MoM algorithm is used to find the incident field which shines on scatters in the near field region,and then the incident field is employed as the source of the GTD algorithm to obtain the disturbed radiation pattern.Numerical results show that the hybrid method of the two algorithms not only extended the use of GTD program,but also effectively solved this type of challenging problems. |
