Abstract

A system that uses elastic surface waves and electromagnetic waves has been developed to detect buried land mines. An algorithm based on local spatial frequency analysis is presented to illustrate the dispersive effect of the land mine on the acoustic waves and to estimate the wave velocity as a function of position and temporal frequency. In addition, an imaging algorithm is presented which calculates the reflected energy and generates a two-dimensional image that localizes the buried mines.
