Abstract:Multiple wave interference is usually existent in the signals recorded by the ground penetrating radar receiving antenna with ultra-wide band. To eliminate the multiple wave interference and improve the signal-to-noise ratio, this paper puts forward ground penetrating radar signal processing based on waveform removal deconvolution, describes its basic principles and implementation method, and analyzes its application range and conditions. To testify this method, the authors carried out a model test, in which PVC pipes 100 mm in diameter were used as calibration models and were embedded in sand. The results show that the multiple interference and random disturbance to the radar signals are apparently suppressed after disposal, the image becomes "clear", and the quality of image is obviously improved.
