| 摘 要： | Hilbert变换为基础的信号分析方法丰富了探地雷达的观测参数，为数据处理提供了更多依据。Hilbert变换针对的是“窄带”信号，对噪声非常敏感，而探地雷达信号不可避免存在噪声，且在频散介质中传播发生频散，其信号有一定的带宽。应用时一频性质较好的小波变换定义相位，较好的克服了这些问题，该方法采用连续复小波变换将探地雷达信号分解为实部和虚部，进而定义相位。

| Abstract: | The signal processing method by Hilbert transform enrich the survey parameter and provide more evidences to the processing GPR data. But Hilbert transform is based on the narrowband signal and very sensitive to noise. However,GPR signal always along with noise,and has certain band for the frequence will be dispersed when electromagnetic wave travel on frequency dispersed medium. These faults were improved by using complex continuous wavelet transform defined the phase which tranformed the GPR signal to real... |
