ABSTRACT:
In a method for detecting objects hidden underground, a plurality of electromechanical transducers including at least one electroacoustic pressure wave generator and at least one acoustoelectric sensor are disposed above a ground structure. Locations of the transducers relative to one another are determined. The pressure wave generator is energized to produce an outgoing pressure wave which is transmitted into the ground structure. Incoming pressure waves reflected by underground surfaces in response to the outgoing pressure wave are sensed and analyzed to determine three-dimensional shapes of underground objects disposed in the ground structure.
