A data analysis method for frequency modulation continuous-wave ground penetrating radar target near-field images using wavelet transform is proposed. And it discusses the instant characteristic of zero interme- diate frequency detected from frequency modulation continuous-wave ground penetrating radar back-wave signals using wavelet transform. Based on the wavelet transform algorithm features: constant Q, fit algorithm and fit mother wavelet. The accuracy of back-wave signals' time-difference detecting and the image bound of target are improved. And the better results from the computing simulation are obtained.
