A pulse electromagnetic inverse scattering imaging detection method suitable for underground cable inspection has been proposed. This method is used for underground cable imaging. This method combines the advantages of high-frequency pulse emission and inverse scattering imaging technology. The nonlinear integral equation of electromagnetic scattering is processed. Meanwhile, the TSVD and Tikhonov hybrid regularization techniques are combined to solve the ill-conditioned problem in electromagnetic inverse scattering, and the images of underground cables or pipelines can be reconstructed. The simulation and experimental results show that the imaging effect of the adopted algorithm is superior to that of the traditional offset algorithm. It provides a non-contact detection method for the path trajectory and burial depth of underground cables or pipelines.
