利用混合法研究目标的双站散射机制

Study on Bistatic Scattering Mechansim of Objects by Using Hybrid Method

本文利用混合法分析了圆柱－劈组合体目标各部分的相互影响，精确地计算了该目标的双站雷达散射截面（ＲＣＳ），从而确定了给定入射角时该目标各部件的相互作用机制。在这种混合法中使用了ＰＯ近似、ＰＴＤ、ＧＴＤ理论和矩量法。本文的讨论表明混合法不但可精确的计算目标的双站ＲＣＳ，而且可用以分折双站散射机制。

Interaction of Parts of cylinder/wedge composite target is studied by using hybrid method, and the bistatic RCS of the object is calculated exactly, then bistatic scattering mechansim is obtained at a given incident angle. In the hybrid method, PO approximation, PTD, GTD and MM are used. It is shown hybrid method can be used to calculate bistatic RCS and to analyse bistatic scattering mechanism.
