| 摘 要： | 提出一种适用于滑动扫描的纯相移滤波方法。通过对记录或者统计得到的可控震源力信号进行分解,得到各次谐波分量,然后通过对地震道记录按照各次谐波的相移量进行纯相移处理。对相移后的结果,设计合适的滤波器,消除谐波。结果表明,所提方法稳定、高效、易于实现,只需要知道可控震源力信号和每一炮的初至时间,就可以在滑动扫描记录中有效消除谐波干扰,适用于对野外采集数据进行实时处理。 |
| 关 键 词： | 地震资料处理 滑动扫描 谐波畸变 纯相移 |

| Abstract: | A new method of eliminating harmonics for slip sweep recording was presented using the pure phase shift filter.The phase spectrum of each harmonic components from the ground force obtained by recording or statistics was computed.Then the procedure of pure phase shift operation was taken and a favorable filter was designed to eliminate the harmonics.The results show that this method is robust,fast and can be easily implemented.Using only the ground force and the start times of the sweeps,it can remove the harmonics in slip sweep data effectively,and it is applicable for real-time processing. |
| Keywords: | seismic data processing slip sweep harmonic distortion pure phase-shift |
