Abstract :
For subsurface detection by UWB GPR, one of the big challenge is to eliminate background clutters. In this paper, a wavelet packet based de-noising algorithm driven by best-tree for UWB GPR data is developed. We introduce the procedure of the de-noising algorithm, and present the experiment result of iron pipe B-scan de-noising. Later, provide the suggestion for future work.
