时域有限差分(FD-TD)法是麦氏方程的差分形式的数值解法,用于求解任意复杂目标与电磁场的相互作用问题。本文把这一理论应用于地质雷达的数值模拟,得到满意的结果。
The FD-TD method is a numerical solution of the differential form of the Maxwell equation and is used to solve the interaction problem between any complex target and the electromagnetic field. This paper applies this theory to the numerical simulation of GPR, and obtains satisfactory results.
