良好的结果也验证了二维时域有限差分法(2d - FDTD)正演模拟的可行性。
Good results also verify the feasibility of forward modeling with two-dimensional finite difference time domain method (2d-fdtd).
因此，通过不同环境的试验得到雷达图谱特征，并利用二维时域有限差分法对其进行正演模拟。
Thus, we obtained characteristics of radar images by experiments in different environment, and implemented forward modeling using two-dimension finite difference time domain method.
