The maximum likelihood criterion is equivalent to the minimum root-mean-square error criterion when the supposed noise is Gaussian white noise of average value of zero.

在拟速度测井中,地震子波是根据信号检测理论的最大似然估计方法来估算的。当假设干扰是均值为零的高斯白噪音时,最大似然准则等效于最小均方误差准则,求取地震子波的最大似然估计值就是求解一个托布里兹方程组。在假设干扰为其它情况时,可引出另外的方程组。本文仅讨论了最简单的均值为零的高斯白噪干扰情况。子波处理是将地震记录中既非零相又非最小相位的子波处理为零相子波,进而处理为最小相位子波。这样可提高记录的讯噪比,使拟速度测井结果更为精确。其中间结果(零相子波记录)在地震解释中极为有用。
