通过滤波来压制噪声、加强有用信号是地震数据处理的重要任务，传统的时变滤波一般是采用分段时窗方法．在ＣｌａｅｒｂｅｕｔＪＦ方法的基础上提出一种现速度逐点变化的滤波方法，并应用干地震勘探数据处理．
Suppression of noise by filtering, strengthening the useful signal is an important task of seismic data processing, the traditional time-varying filtering is generally the use of segmented window method. On the basis of ClaerbeutJF method, a filter method of point-by-point change of velocity is proposed, and dry seismic exploration data processing is applied.
