吸波涂层目标散射特性的复射线分析
COMPLEX RAY ANALYSIS OF SCATTERING FROM RAM COATED TARGETS
-
摘要: 将复射线理论推广到媒质有耗的情形,可以建立起损耗媒质中的复射线方法并用来分析吸波涂层目标的散射特性。该方法具有计算简便、物理概念明确、适用范围较广等特点。本文以涂层金属平板为例所进行的目标雷达截面分析结果表明,理论计算与实验结果能够很好地吻合。

Abstract: With the extension of complex ray theory (CRT) from lossless media intolossy ones, the complex ray analysis in lossy media can be constracted, and effectively used in the problems of scattering analysis of objects coated with radar absorbing materials (RAM). This method has advantages, such as simple calculation procedure, clear physical meaning, wide applicanon area etc. As an example, the radar cross-section (RCS) of conducting flat plates coated with RAM is analyzed. The results show that the theoretical predictions agree very well with the experimental results. -
