摘要
结合时域有限差分法、物理光学法以及非均匀媒质射线跟踪方法,研究了电推进羽流对卫星电磁传输环境的影响,开发了一款电推进羽流电磁效应仿真软件。因软件采用低频与高频算法相结合的计算构架,故可为这类问题分析提供宽频域的解决方案。最后,通过C#平台对所编制程序进行交互设置,为羽流-卫星系统电磁特性分析提供了一种便捷的手段。研究结果对推动仿真软件国产化可起到一定促进作用。
Combined with the finite difference time domain,physical optics and ray tracing in inhomogeneous media,the influence of the electric propulsion plume on the electromagnetic transmission environment around the satellite is studied,and the simulation software for the electromagnetic effect of the propulsion plume is developed.Because the algorithm uses a computational framework based both on the low-frequency algorithm and high-frequency algorithm,it can provide a broadband solution for the analysis of such problems.Finally,using C#platform,a convenient operation interface is obtained,which can provide an effective numerical simulation method for the analysis of the local electromagnetic environment of satellite,and make up for some deficiencies in this field.
