雷达截面的理论分析方法

The Methods for theoretical Analysis of Radar Cross Section

介绍了过去几年内作者对飞行目标部件和整机雷达截面分析所采用的理论方法和取得的进展。分析的关键部件包括：天线、天线罩、进气道、机身机翼及翼身结合部一体化；方法包括：几何光学法、复射线法、物理光学法、等效电磁流法、绕射理论、矩量法与场量迭代法等。

In this paper,the theoretical methods and the progress used by the present authoras for the analysis of radar cross sertion of the kiy parts and the whole aircrafts are introduced.The Key parts analysed include antennas,radomes,inlets,bodies,wings,fins and their combinations;the main methods used are GO,the complex ray methods ,PO,the equivalent EM currents method mthe theory of diffracted fields and thefield iteration method.
