The invention discloses a method for constructing a guided filter to suppress acquisition footprints based on a statistically coherent important body. The method comprises defining the similarity s(t)of J seismic traces u(t) in 2k+1 sampling vertical analysis windows as a ratio of the energy of a mean trace to the average energy of each trace; approximating the statistic F by the degrees of freedom d1 and d2 and a non-central parameter [lambda]; obtaining a relationship between the similarity and the statistic F; and filtering the data by an edge-preserving structure directional filter. Themethod has a good filtering effect.
