Multiple attenuation using an apex-shifted Radon transform

Multiples from sea-floor scatterers and peg-leg multiples in complex<br>geology are often resistant to conventional multiple removal<br>techniques such as Radon demultiple. They have a<br>complicated moveout behaviour in prestack gathers which can only be<br>approximately represented by a conventional parabolic or<br>hyperbolic Radon decomposition.
