1. A system for locating and identifying buried conductive bodies, comprising:
- a waveform generator;
a receiver including at least one sensor arranged to detect electromagnetic radiation emitted by a buried conductive body when a waveform generated by said waveform generator is impressed upon said conductive body;
a processing unit and a display;
wherein said waveform is time-duration limited and said processing unit is arranged to enable identification of said conductive body based on deviation of a waveform of said electromagnetic radiation from said original waveform, and wherein said processing unit is arranged to locate said conductive bodies based on relative amplitudes of said waveform of said electromagnetic radiation detected by said at least one sensor.

Abstract
Both location and identification of a buried or otherwise hidden conductive body is achieved by impressing a known electromagnetic waveform upon the conductive body, using at least one sensor to detect radiation emitted by the conductive body in response to the impressed waveform, locating the source of the emitted waveform based on comparison of the amplitudes of signals received by the at least two sensors, and evaluating the emitted radiation for deviations from the impressed waveform in order to determine the pattern of distortion caused by the conductive body and thereby identify the conductive body.
