Claim 6:
7. A method for determining a subsurface feature, comprising:
transmitting a surface penetrating radar (SPR) signal at a ground surface;
receiving a response signal that includes elastic waves of a lower frequency acoustic source that interact with the SPR signal;
rapidly processing the response signal including the SPR signal modified by the interaction with the elastic waves; and
determining a physical characteristic of the subsurface feature from the response signal;
performing a stacking operation, wherein a signal-to-noise ratio is increased by stacking repeated acoustic pulses and/or probing radar signals; and
performing a dynamic multi-wave imaging operation that provides for detecting small-scale spatially varying signatures through active perturbing and probing of mechanical properties in order to characterize subsurface structures.
