利用快速Hartley交换较快速傅氏变换有更高的计算效率达一特点，本文给出了一种基于Hartiey变换的弹性波逆时偏移算法。该方法与其它逆时偏移算法相比，具有速度快、省内存等优点，并在村位移场（U）成像的同时，能方便地给出体变系数（θ）及协变系数（s）的成像结果。模型试算的结果表明，该方法是可行的。
The use of fast Hartley exchange faster Fourier transform has a higher computational efficiency of a feature, this paper presents a Hartiey transform based on the elastic wave inverse time migration algorithm. Compared with other inverse time migration algorithms, the proposed method has the advantages of fast speed and provincial memory, and can easily provide the coefficient of variation (θ) and the covariance coefficient (s) ) Of the imaging results. The result of model trial shows that this method is feasible.
