Abstract

For the detection of a buried object we consider two straight thin-wire antennas above an interface between two homogeneous dielectric half spaces. One antenna is a transmitting wire and the other is a receiving wire. Our aim is to use this simple antenna set up for the detection of buried objects without applying pre and post processing of the received signal. The buried wire can be detected directly from the shape of the current at the receiving antenna. To minimize the effects of repeated reflections at the end faces of the wire antennas, pulse compensation is introduced. Numerical results show that with the aid of pulse compensation a buried wire can easily be detected.
