摘要
首先应用FDTD在二维空间内计算了土壤的时域散射场,并与理论公式进行比较,在一定精度下,二者吻合得较好。进一步用GPML吸收边界模拟探测地下管道,并给出了不同深度、不同直径的管道散射的数值结果。
An analysis of time-domain scattering field has been given in soil with 2-D FDTD, and the numerical results are verified by comparing with the theory.The detecting of the underground pipe was simulated by using GPML absorbing boundary condition,numerical results of scattering of pipe are given in different sizes and different depths.
