Abstract
A method of detecting conductive bodies in an area wherein a primary field having a complex waveform, such as a frequency modulated, rapidly swept signal is generated and is radiated toward the area. A receiving system is provided for sensing the primary and secondary fields. Computerized signal processing techniques are used to obtain the best match between the waveforms of the received signals and those of stored reference waveforms which correspond to responses of known conductive bodies.
