Method and apparatus for detection and logging of buried objects and subterranean anomalies

摘要

A method and apparatus for the detection of buried objects and subterranean anomalies using detector technology including, for example, existing metal detector technology is provided. A grid having defined coordinates is established over a desired search area, and a survey is conducted over the desired search area using a metal detector. Output data generated by the metal detector are assigned values, and such values are correlated to the various coordinates of the search area. A converter is used to convert an audible analogue signal of existing metal detectors to digital values. Such digital values are then plotted against coordinates of the search area in order to develop a graphical representation or map of the search area. The graphical representation can be used, together with other information from the metal detector, to discern qualitative characteristics of buried objects and/or subterranean anomalies encountered in the search area.
