Towards wavelet transforms part characters in time domain and frequency domain, a practical GPR signal processing method is proposed. Based on continuous wavelet transform, the main component of echo signal is extracted by energy analysis. Through scaled decomposition and frequency filtering, the disturbed component is eliminated. The SNR of reconstructed echo signal is improved. The experiments of real data indicate it improves the processing performance of underground target detecting than continuous wavelet transform.
