The influence on signals de-noising with the multiwavelets pre-processing methods is discussed and investigated in this paper. The de-noising effect of ground penetrating radar (GPR) image with multiwavelets based on different pre-processing methods and an improved thresholding function is analyzed and compared. The results of simulation experiment indicate that the de-noising effect of GPR image with DGHM multiwavelet based on proper pre-processing methods is better than those traditional methods.
