摘　　要：利用Likas等处理图像恢复的变分法来讨论地震记录反演中的盲目反褶积问题.利用Kullback-leibler信息测度获得一个非常有用的统计函数(即变分函数),此函数的极值点就含有所要求的子波及反射系数序列,并且拟订出求此泛数极值点的一套算法.In the inversion of the seismic, solving the problem on a blind deconvohtion is pretty difficult. There are various methods to discuss this problem, such as the method of the cumulant moments etc. In this paper, the problem on a blind deeonvolufion in the seismic is discussed by using the functional method, by which Likas et al studied the problem on the restoration of an image. A statistical function（i, e. the variational function）, the maximum point of which includes the wavelet and the coefficient sequence of the reflecfions, is obtained by using the Kullback-Liebler information measure, and the algorithm is devised for computing the the maximum value of the variational function.
