摘要
针对战场电磁环境的可视化,提出了一种计算战场电磁环境的方法。运用时域有限差分法对电磁环境建模,并构造出边界吸收条件,对于近场直接利用时域有限差分法(finite difference time domain,FDTD)求解近场电磁数据,对于远场则要通过近远场变换求取电磁数据。该方法为战场电磁环境可视化提供了数据支持。
Aiming at battlefield electromagnetic environment visualization,a computation method of battlefield electromagnetic environment is presented.Firstly,establish model of the battlefield electromagnetic environment with FDTD,then construct the absorbing boundary.Finally,acquire the electromagnetic data by FDTD and the transformation from the near field to the far field.This method can support battlefield electromagnetic environment visualization with data.
