Abstract: In the inversiontithe seismic，solving the problem on a blind deconvohfionis pretty dificult．There are various methods to discuss this problem．such as the method ofthe cumulant moments etc．In this pflper，the problem on a blind deeonvolufion in the seismicis discussed by using the functionai method，by which Likas etal studiedthe problem onthe restoration of an image．A statisticalfunction(i．e．the varianction)，the maximum point of which includes the wavelet and the coeficient sequence of the reflections，is obtained by using the Kullback-Liebler information measure，and the algorithm is devised for computing the the maximum value ofthe variational function.
