采用点线模型法建立二维复杂目标的几何模型 ,运用 Mo M- CGM- FFT相结合的混合技术 ,结合可视化编程技术 ,形成“二维复杂目标的电磁极化散射的建模与仿真”软件。这使得几何模型的建立和仿真的速度有了很大地提高 ,大大降低了内存需求和仿真时间。最后运用该软件对一个复合柱体进行了仿真 ,给出了仿真结果 Using the point-line model method to establish the geometric model of two-dimensional complex targets, the hybrid technique of Mo M-CGM-FFT and the visual programming technology are used to form the software of modeling and simulation of two-dimensional complex electromagnetic polarization scattering . This has greatly accelerated the creation and simulation of geometric models, greatly reducing memory requirements and simulation time. Finally, the software was used to simulate a composite cylinder, and the simulation results were given
