1. A method for detecting buried objects, the method comprising:
- receiving ground penetrating radar (GPR) signals captured at discrete locations along a surface of a medium in which an object may be buried;
computing a maximum power spectral density (PSD) value for each received GPR signal, the maximum PSD values being indicative of the proximity of a buried object;
plotting the computed maximum PSD values as a function of location along the surface of the medium;
determining an apex of a hyperbola that results from the plotting of the computed maximum PSD values; and
designating a location along the surface of the medium at which the apex occurs as an estimated location of the buried object.

Abstract
In one embodiment, a method for detecting buried objects includes receiving ground penetrating radar (GPR) signals captured at discrete locations along a surface of a medium in which an object may be buried, computing parameters based on the received GPR signals that are indicative of the proximity of a buried object, plotting the computed parameters as a function of location, determining an apex of a hyperbola that results from the plotting of the computed parameters, and designating a location at which the apex occurs as an estimated location of the buried object.
