| 摘 要： | 常见的几种地震子波有:零相位子波、最小相位子波、最大相位子波和混合相位子波。以不同类型的信号为激发子波,对不同地层模型合成地震道。仅用原始合成地震道记录的振幅谱来恢复原始记录,讨论不同方法下,由于激发子波的不同,对比分析原始记录与恢复记录的差异,及其恢复效果。

| Abstract: | General seismic wavelets,the wavelet of zero phase,minimum phase,maximum phase and mixed phase,are simulated and as being shooting wavelet.We can get different synthetic seismograms using various stratigraphic models.The resurgent technology of signals only depends on the amplitude spectrum of the synthetic seismograms.The authors analyse the difference effects of above ways. |

| Keywords: | wavelet simulating amplitude spectrum phase spectrum synthetic seismogram signal reconstruction Fourier transform |
