Application of Synchrosqueezing Short Fourier transform analysis in Ground Penetrating Radar thin layer Recognition

In order to meet the need of actual exploration, this paper makes a deep study of the thin layer's electromagnetic reflection properties. The Synchrosqueezing Short-Time Fourier Transform (SSTFT) is introduced into the thin layer identification. This method is highly adaptive to the given signal and makes the time-frequency plot more sharpen. Even the layer with the thickness of $\lambda/8$, the SSTFT analysis method can still pick up the top and bottom of the layer. The experiment on the and real data show that the method improves the time-frequency resolution and the layer recognition ability of the Ground Penetrating Radar signal.
