Abstract In view of the problem of the Radon domain energy group energy leakage,this paper proposes a multiple attenuation method based on high-resolution Radon transform.The authors employed sparse constraint operator on the basis of conventional hyperbolic Radon transform,which can improve the degree of focus of velocity spectrum and better separate effective and multiple energy groups.Model and real data tests show that the proposed method is effective and applicable.
