Abstract : Because of current efforts to clean former artillery ranges, there exists a need to develop an electromagnetic system to locate and identify subsurface artillery shells. Current ground penetrating radars are inadequate for the task because they are unable to couple sufficient energy into the ground without making an electrical connection to the earth. Here, we propose a ground coupling radar using an antenna with a predominately magnetic near field. The proposed radar will position the air-earth boundary in the near field of the antenna to couple energy into the ground. The proposed system depends on the enhanced coupling which occurs at the fundamental resonant frequency of the shell for detection and identification. Here we report on initial numerical and experimental studies to establish the feasibility of the ground coupling radar.
