Application of FDTD Numerical Simulation of Ground Penetrating Radar in Urban Road Detection
Ground penetrating radar(GPR)has gained widespread application due to its simplicity,rap-id 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.
