“…The mathematical description of this operator is similar to the kinematic post-stack time migration equation, with the horizontal coordinates being offset rather than midpoint. ASHRT has found applications in various areas, including deblending [17], micro-seismic data denoising [18], the separation of diffractions and reflections [19,20], and attenuation of multiples [21,22].…”

The apex-shifted hyperbolic Radon transform (ASHRT) based on the Stolt-stretch operator can be implemented in the frequency domain, which accelerates the computation efficiency of ASHRT. However, the Stolt-stretch operator has limitations when it comes to velocity variations. Therefore, this paper introduces a new ASHRT approach based on post-stack phase shift plus interpolation (PSPI) imaging and modeling operators. This new approach is designed to better adapt to changes in medium velocity and enhance the quality of data reconstruction. When combining this novel transformation with sparsity constraints for model testing and real data applications, the experimental results indicate that it is an effective data reconstruction tool, with superior data reconstruction results compared to traditional ASHRT based on the Stolt-stretch operator.
