| 摘 要： | 通过对S变换与短时傅立叶变换的对比,证明S变换具有多分辨率及自适应的特点,并将其应用于某岩溶场地勘察,对实测资料进行处理和解释。通过实例应用的分析表明,S变换的时频切片图中的异常反应比在时间剖面中的反应更清晰,对确定异常的位置、规模等都有很好的效果,有利于提高映像资料的解释准确性和精度。

| Abstract: | Based on the comparison of S transform and short time Fourier transform,the S transform is proved to have the features of multi-resolutions and adaptive ability,and it is applied to a karst exploration project for processing and interpreting the measured data.The analysis shows that the abnormal reflection on the time-frequency slice map of the S transform is clearer than in the time section,which is useful for locating the abnormal position and scale and good at improving the accuracy and precision in the imaging data interpretation. |
