摘要
随着系统仿真技术的快速发展,复杂电磁环境(CEME)已然引起人们的广泛关注,CEME仿真对于雷达预警、体系对抗、移动通信、GPS定位等都有重要作用。首先对于二维抛物方程(2DPE)的推导过程及离散过程进行介绍,并对2D电磁传播的衰减过程进行了仿真。其次,基于2DPE法,研究了并行度高的准三维抛物方程(quasi-3DPE)仿真方法。最后,通过仿真案例,验证了准三维法仿真的三维效果和并行效率,总结比较了3DPE和quasi-3DPE法的计算效率和精度,并借助商业电磁仿真软件Wireless Insie验证了quasi-3DPE法的传播损耗仿真精度。
With the fast development of the system simulation technology, electromagnetic environment （EME） has already been widespread concerned, which plays an important role in the EME simulation for radar warning system confrontation, mobile communication, GPS positioning, etc. First, the derivation of the two-dimensional parabolic equation （2DPE） and discretization process are introduced, and the attenuation of the 2D electromagnetic propagation process is simulated. Secondly, based on 2DPE method, the quasi-three-dimensional parabolic equation （quasi-3DPE） method is studied, which is easy to be paralleled. Finally, through the simulation case of quasi-3DPE method simulation of3D effects and parallel efficiency, the calculation efficiency and accuracy are summarized by the comparison of 3DPE method and quasi-3DPE method, and verified with Wireless Insite, commercial electromagnetic simulation software.
