Abstract

A particularly difficult problem in using GPR for land mine detection is the shallow depth at which many mines are buried. The scattered energy from a mine may be very small, whereas the specular scattering form the surface, as well as the direct coupling between transmitter and receiver, are often quite large. If the mine is shallow, the difference in propagation delay between these responses is very small, and resolving the mine form the specular surface reflection is difficult. Even if the radar bandwidth is sufficient to resolve closely spaced targets, detecting the smaller target is problematic.
