Wavelet transform is one of new signal analysis tools, it plays an important role in numerous fields such as image and graphic processing, data compression, gravitational and geomagnetic data processing... In this study, the continuous wavelet transform and the wavelet transform modulus maxima method with appropriate wavelet functions were used to determine the underground targets from ground penetrating radar data. Results of this technique from the testing on theoretical models and experimental data indicated that this procedure was a feasible method; and it can be used for detecting the depth, size and position of the buried objects without the consideration of electromagnetic wave velocity in the material. This ground penetrating radar analysis can be also applied for the detection of natural resources in shallow structure researches.
