摘    要:空腔结构是目标最重要的强散射源。本文综述了分析空腔高频散射的四种主要方法,即导波模式法,几何光学法,高斯波束法和复射线法。概述了这些方法的原理,给出了典型的数值结果,比较了它们的优缺点及适用范围。

关 键 词:电磁散射  空腔结构

Abstract:Open-ended cavity,which may wen simulate an engine inlet,is one of the most strong scatteringsources of targets.In the present paper,four main approaches for theoretical prediction Of this ecatteting construction are investigated,including waveguide mode approach,geometrical optics,Gaussian beam technique,and complexray method.Their principles and typical numerical results are given,and some pram and cons of these approaches arediscussed.
Keywords:Radar target  Radar cross section  Electromagnetic scattering  High-frequency technique
