电磁导弹在任意二维金属目标上的后向散射

BACKSCATTERING OF ELECTROMAGNETIC MISSILES BY A PERFECTLY CONDUCTING CYLINDER WITH ARBITRARY CROSS SECTION

研究任意二维金属目标对二维电磁导弹的散射规律。研究结果表明,当一个能量衰减速率为r^-(0<8<1)的电磁导弹投射到金属目标后其后向散射场能量衰减速率将正比于r^-R/(2r+R),其中R为目标镜像点处的曲率半径。

In this paper, we present a general study on backscattering of electromagnetic (EM) missile by a perfectly conducting cylinder of arbitrary cross section. We find that, when an EM missile with energy decreasing as r-8 (0 < δ < 1) is projected upon the conducting target the rate of energy decay of the backscattered field will be proportional to r-8R/(2r + R), where R is the radii of curvature at tie specular point of the target.
