variable-difference method

Variable velocity DMO formula which is analOgous to constant velocity DMO formula and Hale's squeezing DMO is derived from the time-distance equation of CRP gather data-The method is a revised version of constant velocity DMO;

本文从共反射点时距曲线方程出发，导出了类似于常速DMO公式的变速DMO公式（与Hale等称之的squeezingDMO相类似）。
