Application of Lifting Wavelet Transform to Ground Penetrating Radar Signal Denoising Based on Improved Threshold Value

Xu Houlei1,2 Chu Dongdong3(1.State Key Laboratory of Hydrology-Water Resources and Hydraulic Engineering,Hohai Univ.,Nanjing 210098,China;2.National Engineering Research Center of Water Resources Efficient Utilization & Engineering Safety,Hohai Univ.,Nanjing 210098,China;3.Jiangsu Hydraulic Research Institute,Nanjing 210017,China)  
For the characteristics of noise and peak or mutation-shaped non-stationary signal which exist in the ground-penetrating radar signal acquisition,based on the lifting algorithm,the wavelet transform denoising method is introduced;taking into account the deficiency existing in traditional hard and soft threshold function,a new improved threshold function is proposed.Through analyzing the denoising effect of two-dimensional ground-penetrating radar simulation model and considerations of calculation time and denoising effect,it is found that the threshold increase based on improved wavelet transform denoising in ground penetrating radar signal has a certain value.
