forward time difference

基本解释

Good results also verify the feasibility of forward modeling with two-dimensional finite difference time domain method (2D-FDTD).
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。
At the same time, the time forward difference scheme may be stable also after adding frictional term, but the frictional coefficient required is then much larger.
并且时间向前差的格式在加上粘性项后也可以稳定，但要求的粘性系数过大。
Thus, we obtained characteristics of radar images by experiments in different environment, and implemented forward modeling using two-dimension finite difference time domain method.
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。
