Initial Numerical and Experimental Studies to Develop a Ground Coupling Radar forLocation and Identification of Unexploded Artillery Shells

摘要

Because of current efforts to clean former artillery ranges, there exists a needto develop an electromagnetic system to locate and identify subsurface artillery shells. 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. We report on initial numerical and experimental studies to establish the feasibility of the ground coupling radar.
