| 摘 要： | S变换自问世以来，凭借其优越性已经被广泛地应用于数字信号处理中。对模拟的探地雷达数据和实测的探地雷达数据进行S变换时频分析。其中探地雷达数据的模拟采用时域有限差分法，地电模型为层状介质，通过S变换时频分析，可以更有效地区分薄层状介质。对实测的探地雷达数据进行S变换时频分析，去除了部分噪音干扰，突出有效信号，图像更直观，易于图像的解译。

| Abstract: | S -transform since the emergence, by virtue of their superiority has been widely used in digital signal processing. The simulation of ground penetrating radar data and measured ground - penetrating radar data is used for S - transform time - frequency analysis. Ground - penetrating radar data simulation using finite difference time domain method and the electrical model for layered media, through the S - transform time - frequency analysis,it can more effectively distinguish thin - layer media. Measured GPR data through S -transform time -frequency analysis, it can eliminate some noise interference, highlight effective signal, image more intuitive and be easier to image interpretation. |
