Using ground penetrating radar time-frequency analysis methods to recognise thin-layer

Time-frequency analysis method to locate the thin layer in GPR detection is proposed in this paper. It is used to improve the recognition ability of GPR. Several time-frequency analysis methods as Short Time Fourier Transform (STFT), Wavelet Transform (WT), S Transform, General S Transform and Wigner Transform are compared in this paper. Simulation and experiment results verify the effectiveness of the proposed method.
