Abstract
This paper presents a multiple suppression algorithm based on the decomposition of seismic data into wave packets. The algorithm is based on high-resolution Radon transform and Gaussian wave packets transform. High-resolution Radon transform allows you to separate single and multiple reflected waves due to the increased resolution of the transformation in comparison with the standard approach. Having selected multiples in the Radon region, the task is set to correctly subtract them from the original seismic record. Decomposition into Gaussian wave packets allows adaptive subtraction of multiple reflected waves from a seismic record, including those in interference zones, without losing the target signal. The algorithm was tested on synthetic and real data. Testing shows effective multiple attenuation comparable to those used in seismic data processing software.
