摘要:
为精准判断围垦堤防架空隐患的位置和范围，结合探地雷达检测技术的优点，基于时域有限差分法（FDTD），对探地雷达电磁波的传播特征进行数值模拟分析。主要研究时域有限差分法的差分形式、二维空间内的时域差分方程、数值稳定性及吸收边界条件的设定等问题。对围垦堤防可能存在的几种隐患形式进行正演模拟，通过分析雷达电磁波幅值变化，讨论其相应的剖面图像特征，并通过开展室内模拟试验和现场检测工作研究对正演模拟结论进行验证。研究结果表明：正演模拟可实现探地雷达典型形状目标的识别，为提高现场检测图像解释的精度和准确性提供理论参考。
Abstract:
In order to accurately determine the location and scope of the hidden danger of overhead in the reclaimed embankment,combined with the advantages of the ground penetrating radar (GPR) detection technology,the propagation characteristics of the electromagnetic wave of GPR were numerically simulated based on the finite-difference time-domain method (FDTD).The difference form of FDTD,the time-domain difference equation in two-dimensional space,the numerical stability and the setting of absorption boundary conditions were mainly studied.Several possible hidden dangers of reclaimed embankment were simulated by forward modeling.Through analyzing the change in the amplitude of radar electromagnetic wave,the corresponding profile image characteristics were discussed,and the results of forward modeling were verified by laboratory simulation tests and field testing.The results showed that the forward modeling could realize the recognition of typical shape targets of GPR,and provide theoretical reference for the precision and accuracy of image interpretation in field detection.
