摘要
地质雷达因其操作简单、探测快速、分辨率高,而得到了广泛应用。该文应用时域有限差分数值模拟算法,对城市道路探测中不同形状、物性的目标地质体进行数值模拟,总结了雷达波形图的特征反映,为解释推断提供了依据。最后,通过实际工程案例,验证了地质雷达FDTD数值模拟方法在城市道路探测中的有效性和可靠性。
Ground penetrating radar(GPR)has gained widespread application due to its simplicity,rapid detection capability,and high resolution.This paper employs the finite-difference time-domain(FDTD)numerical simulation algorithm to model different various shapes and physical properties of target geological bodies in urban road detection.The study summarizes the characteristic reflections in radar waveforms,providing a basis for interpretation and inference.Finally,an actual engineering case verifies the effectiveness and reliability of the GPR FDTD numerical simulation method in urban road detection.
