对根据地震勘探数据估计出的速度场进行平滑常常是非常有用的。例如,当采用精确而平滑的偏移速度场时,地震偏移就能相当成功。我们用北海的速度资料对一维、二维和三维平滑作了检验。对大量的平滑技术检验的结果表明,局部加权回归技术 It is often useful to smooth the velocity field estimated from the seismic data. For example, a seismic offset can be quite successful when using a precise and smooth offset velocity field. We test the one-dimensional, two-dimensional and three-dimensional smoothing with the North Sea velocity data. The results of a large number of smoothing techniques show that the local weighted regression technique
