Abstract

Ground detection radar detection technology is an effective and feasible nondestructive testing technology for the quality inspection of reclamation embankment engineering. It has the advantages of high detection precision, high speed and continuous detection, but it is restricted by environmental conditions, which reduces the detection efficiency. Based on the FDTD algorithm, the forward modeling of overhead hidden danger in the reclamation embankment is carried out, and the typical radar image is obtained. The radar image characteristics of the reclamation embankment are summarized, which provides a theoretical basis for the application of ground penetrating radar to identify abnormal bodies in engineering practice.
