Subterranean Anomalies Detection System.
Abstract
This patent application describes a method and apparatus for detecting anomalies beneath an area of the earth's surface wherein an oscillator couples a current into two conductors laid parallel to each other to generate two magnetic fields in the earth beneath the area. The magnetic field is measured along a line midway between the two horizontal conductors to detect for an increase in the measured field which is an indication of the presence of an anomaly. (Author)
