| 摘 要： | 基于有限差分法，建立了探地雷达电磁波在河道传播的正演模型，并模拟了水下不同构造的典型工况，得到了相应的二维反射图像。和实际探测的河道图谱进行了比较，通过对模拟图像的分析和实际雷达探测图谱的解释，研究了探地雷达方法在河道探测中的可行性。

| Abstract: | Based on the finite difference method,the authors established the forward model for the ground-penetrating radar electromagnetic waves propagation in the river,simulated the typical conditions of different underwater formations,and obtained the corresponding 2D image.Through a comparison with the actual detecting reflected image of the river and an analysis of the simulation image and the interpretation of the actual radar detection image,the feasibility and rationality of the ground-penetrating radar method in detecting the river course were studied. |
