Visualization Computing of Radar Objects in Resonance Region of RCS
-
摘要: 随着计算机进一步发展,科学计算可视化越来越受到重视;而适用于低频区RCS(雷达散射截面)计算的传统方法MOM(矩量法),也越来越显示其价值;为了方便电磁计算和电磁建模,基于先进的计算机三维造型技术和可视化编程手段,采用回路线栅矩量法,计算低频区三维雷达目标RCS,与实验数据比较取得良好的计算结果,对RCS理论计算的工程应用起重要作用.Abstract: With the development of visualization in scientific computing, traditional MOM for low frequency RCS has been re-evaluated. By means of advanced 3Dmodeling technology, a loop circuit method for solving the scattering field of 3Dtargets in resonance region is presented. The numerical results are in good agreement with experiment data.
