Radar Cross Section Reduction and Characteristic of Electromagnetic Pulse in Antiradar Coating Material

讨论在被探测目标表面涂敷雷达波吸收材料时 ,电磁脉冲在损耗媒质中的传播与雷达散射截面减缩的问题 .首先研究电波在两层损耗媒质中电磁波的反射和透射 ,通过对复反射系数的研究 ,得到了一些有价值的结果 .然后再研究电磁波在 3层乃至更多层损耗媒质中的反射和透射 ,得出了有用的表达式 ,它便于雷达散射截面的计算 。

The characteristic of electromagnetic pulse in antiradar coating material is discussed in RCSR. When electromagnetic waves are incident on a stratified medium composed of two homogeneous layers, there are reflectonal and transmissible waves. Makes a study of complex reflectional coefficient, the useful results are gained. Then studying stratified medium composed of three or more homogeneous layers, the formulae are obtained. It is obvious that the formulae are applied to RCSR.
