Experiments on a detector array for real-time location of buried objects

Experiment· were conducted to measure the response characteristic· of a detector system consisting of an array of two electromagnetic pulse induction tensor·. Laboratory data for three object : (1)a ıteel sphere (2) a steel prolate spheroid and (3) an 81 mm mortar casing are presented in order to discuss how the response of an object varies with its depth, orientation and lateral offset from coil centres. Relevance of these result· to developing algorithms for location of metallic objects are also pointed out. Finally, data obtained from a scan over buried targets are presented to illustrate a practical application.
