| 摘 要： | 通过研究探地雷达信号的小波变换的模特征点的变化规律和特征,揭示了探地雷达信号奇异点和其小波变换模极值的关系。通过这些关系的研究,对小波各级分解的模特征点进行变频域处理。最后对处理后的地质雷达信号,利用非线性最小二乘方法求解李氏指数,从而进行地质体边界的检测。无论从理论模型的论证还是实际资料的处理都取得了较好的结果。

| Abstract: | The connection of the Georadar data sever and the characteristic points of the wavelet transform model is revealed by means of studying the features and rules of characteristic points of the seismic data wavelet transform model. Based on the above studies, the authors processed the characteristic points of the transform model at all levels. With these achievements, we can obtain better results in tackling the nonlinear problem. |

| Keywords: | wavelet transform characteristic points of wavelet transform Lipschitz index Georadar data |
