Seismic Interferometry by Multi-Dimensional Deconvolution Free from Point-Spread Function

Abstract Seismic interferometry (SI) can be used to reconstruct a pseudo-acquisition from response of passive source, while the reconstructed data recover portion model space that is different recovered by inversion original measurements. The SI crosscorrelation requiring seismic wave field evenly distributed, which limits scope application this method. multi-dimensional deconvolution (MDD) broken through limitation must but there are still some limitations in special practices. Interferometric point-spread function (PSF), like correlation function, necessary condition MDD method, practices it cannot derived data. A new method proposed paper free PSF, and theoretically proved equivalent usual MDD. We demonstrate effectiveness with two numerical examples one-sided illumination, source blurring phenomenon results effectively eliminated. first example far-field one-side also treated MDD, comparison shows methods equally effective. second near-field only because PSF obtained.
