摘要
针对传统数值算法分析天线结构项单站雷达散射截面(Radar Cross Section,RCS)问题运算量大的缺点,基于压缩感知理论引入一种包含各个离散入射角度信息的新型激励源,借助有限元软件的建模分析功能,形成一种适用于处理复杂天线结构项单站RCS的快速算法.通过对单极子天线、角锥喇叭天线和抛物面反射天线等算例的仿真,验证了新算法处理复杂目标能力强、计算效率高的优势.
A novel excitation source with more incident angle information is proposed based on compressive sensing (CS) theory, to overcome the traditional calculation difficulties. With the help of the Finite Element Software, a fast computational method of calculation mono-static radar cross section (RCS) is presented. The calculation results of monopole antenna, pyramidal horn antenna and parabolic antenna have verified the accuracy and computational efficiency of the new method.
