Summary: | The invention relates to a method for eliminating a distorted signal of a directional seismic wave. A directional seismic wave beam record is filtered by local correlation coefficients of the directional seismic wave beam record and an original center record, so that the distorted signal outside a main wave beam can be eliminated and the undistorted directional seismic wave beam record can be obtained. Compared with the prior art, under the circumstance that the signal-to-noise ratio of original data is low, directional seismic wave data is guaranteed to form high-quality data on an exploration target, and the distorted signal outside the main wave beam is effectively eliminated. The method has an important application value for improving the quality of seismic exploration data under a strong background noise interference condition. |
