摘要
针对电大尺寸复杂目标的建模仿真及雷达散射截面RCS计算的问题,基于物理光学(PO)法与几何光学法(GO)的GO-PO混合算法,通过计算机辅助软件对复杂目标进行建模和RCS分析计算。论述了复杂目标从几何建模、网格划分、拓扑结构数据转换、散射特性分析计算的求解过程,最后,通过对坦克车模型进行仿真计算,解算出坦克车模型雷达截面积分布情况,证明了方法有效性,为坦克车等复杂目标雷达隐身设计提供技术支撑。
Aiming at the problems of modeling and simulation of electrically large and complex targets and RCS calculation and analysis,based on the GO-PO hybrid algorithm of Physical Optics(PO)and Geometric Optics(GO),complex targets are mod⁃eled and RCS analysis and calculation by computer-aided software.The solving process of complex target from geometric modeling,meshing,data conversion of topological structure,scattering characteristic analysis and calculation is discussed.Finally,the radar cross-section distribution of tank vehicle model is calculated through simulation calculation of tank vehicle model.The comparative analysis proves the accuracy of the method and provides technical support for radar stealth design of complex targets such as tanks and vehicles.
