Abstract : An investigation to deter ine the worldwide feasibility of a passive magnetic method for detection of nonmetallic land mines is discussed. The work included ascertaining the natural restrictions imposed upon a passive magnetic detection system by the magnetic properties of soil containing buried mines. A special measuring system was developed by USAERDL for these studies. The report concludes that: (a) Use of a passive magnetic mine det ction syste as a sole means of detection is not feasible in 74 of the world's land surface; in 12 because of insufficient mine-soil susceptibility contrast alone; in 40% because of excessive magnetic anomalous (false) signal effects alone; and in 22% because of both insufficient contrast and excessive anomalies. (b) More sensitive instrumentation will not improve the world-wide feasiblility of pa sive magnetic ine detection systems because severe restrictions are imposed on the use of passive magnetic phenome on by natural magnetic soil properties, and not by ina e uate instrument sensitivity.
