采用滑动时窗求出多个时移值的平均值,即可消除随机干扰和其它干涉波对地表因素的影响,最终得到纵向一致的静校正值。将各时窗内对应于平均时移值的相关函数值连接起来,可得到自适应道集加权系数,用来对静校正后的数据道加权。
The use of sliding time window to find the average value of multiple time-shifted values can eliminate the effects of random interference and other interference waves on the surface and finally get the vertical consistent static correction value. The correlation function values corresponding to the average time-shift values in each time window are connected to obtain the adaptive channel set weighting coefficients for weighting the statically-corrected data channels.
