摘要
采用天线细线核方法对线天线阵列的电磁散射特性进行分析,阻抗矩阵元素计算采用精确的积分函数,并对计算中出现的奇异积分采用半解析方法逼近.文中对几种线天线阵列的雷达散射截面进行计算,数值结果表明:该文方法比Pocklington积分方程法具有更高的计算精度和效率.
The electromagnetic scattering characteristics of wire antenna array were analyzed by the antenna thin-wire kernel method in this paper.The accurate integrable functions were used to calculate impedance matrix elements,and the singularity arising in the computation was approximated by the semi-analytical method.Radar cross sections of several wire antenna arrays were computed.Numerical results demonstrated that the method proposed in this paper was more accurate and efficient than Pocklington integral equation method.
