Abstract

A method for detecting hidden objects utilizes a plurality of electromechanical transducers including at least one electroacoustic pressure wave generator (88) and at least one acoustoelectric sensor (92) above a selected ground or water surface or a surface of an object located underground or underwater. Accordingly, the method is useful for detecting underground or underwater objects. Pursuant to the method, locations of the transducers relative to one another are determined, the pressure wave generator is energized to produce an outgoing pressure wave, and the outgoing pressure wave is transmitted through the selected surface. Incoming pressure waves are detecting which are reflected by hidden surfaces generally below the selected surface in response to the outgoing pressure wave. The incoming pressure waves are analyzed (38) to determine three-dimensional shapes of hidden objects disposed below the selected surface, whether underground or underwater. Various views of the hidden objects are displayable on a video monitor (58).
