Image Enhancement of Ground Penetrating Radar Based on Multiscale Space Correlation

Wavelet coefficients of GPR valid signal and random noise change differently with different scale parameter. Combined with the related principle of coefficients in wavelet space, a multiscale enhancement method of GPR weak signal is proposed in this paper. After elaboration of the basic principle of our method, this paper describes the experiment results on different sections. This method proves to be a quite effective and feasible method not only improves SNR of the valid signal but also suppresses noise.
