摘要
利用电场积分方程(EFIE)的矩量法分析了导体平板上有铆钉的电磁散射问题。铆钉和平板表面采用三角形面元进行剖分,面元上的电流分布用子域基函数表示,用伽略金法将电场方程转化为矩阵方程求解电流系数。数值计算了导体平板上有无铆钉时的雷达散射截面随入射角的变化,结果显示当平板上有多铆钉时,在一定的角度范围内,铆钉对雷达散射截面的影响非常明显并且与铆钉的分布情况有关。
In this paper, the Electric Field Integral Equation （EFIE） in conjunction with the moment method is used to analyze the electromagnetic scattering problem of rivet on the conducting plate. The surfaces of the rivet and the plate are partitioned into triangular cells, the current distribution on the patches is represented by subdomain - type basis function, the EFIE is translated into matrix equation by the Galerkin method, then the current coefficient are obtained. Numerical results of the plate and plate with rivets varying with the incident angles show that the distribution of the rivets affects the RCS pattens in some directions.
