Abstract

The requirements on GPR technology for the application of humanitarian landmine detection are severe; 99.6% probability of detection and low false alarm rate. Trying to meet these challenging requirements, an impulse radar system has been designed specifically for the application of landmine detection. The radar system contains a dielectric filled TEM horn transmitting antenna and a small loop receiver antenna below the transmitting antenna. With this radar system three- dimensional measurements have been carried out over a test site containing surface-laid and shallowly buried landmines. The test site contains antitank and antipersonnel mines of metal and plastic. In order to show the performance of the new radar system we have to produce images of the subsurface. The imaging algorithms must then be tuned to the specific acquisition parameters. More specific, the refraction of the waves at the surface and the acquisition geometry of the transmitting and receiving antenna influence the arrivaltime of backscattered energy related to subsurface objects. Since imaging algorithms are based on coherent stacking over this energy we must take into account these factors. We produce clear images of landmines and other subsurface objects using adapted imaging algorithms on the data obtained with the new radar system.
