Abstract

An apparatus for identifying a buried object using ground penetrating radar (GPR) in a system containing at least one GPR sensor (102), comprises a data processor (104) for detecting spatial correlations in data received from a GPR sensor (102) in the apparatus and an image processor capable of building a data structure corresponding to an image of the buried object from data processed by the data processor (104). A method for identifying a buried object using GPR in a system containing a GPR sensor (102) comprising detecting spatial correlations in data received from the GPR sensor in the system and building a data structure (108) corresponding to an image of the buried object from the received data.
