A kind of non-homogeneous bent ripple 3D seismic data method for reconstructing based on linear Bregman algorithms

The invention discloses a kind of non-homogeneous bent ripple 3D seismic data method for reconstructing based on linear Bregman algorithms, it is characterized in that, extract the isochronous surface of non-homogeneous three-dimensional geological data successively first along two spaces direction, on the basis of the multiple dimensioned multi-direction bent ripple direct transform of two dimension, introduce two-dimensional space nonuniform fast Fourier transform, the non-homogeneous bent ripple inverse transformation operator set up between uniform bent wave system number and the lower earthquake missing data of spatial non-uniform sampling, then solved using linear Bregman algorithms, by selecting suitable threshold factor and dynamic step length, and use soft-threshold operator, accurately Inversion Calculation obtains the uniform bent wave system number of irregular geological data under nonuniform sampling, it is last to carry out conventional bent ripple inverse transformation again, so as to form new method for reconstructing.The resolution ratio and signal to noise ratio of reconstruction signal is greatly improved in the present invention, for instructing complex area Non-uniform Earthquake data acquisition, missing road to have important value in terms of rebuilding.
