Abstract
Marine seismic data can be processed to remove or reduce two or more source side acquisition effects jointly when 1) the effects are placed in the same data domain as the received data and 2) the effects are described using the same basis functions which may signify representing the received data and the effects in the same chosen transform domain. The data effects may include source signature removal, source radiation pattern removal, residual shot noise suppression and data regularization, multi-channel reconstruction or regularization, prediction of sea surface multiples, separation of simultaneous sources etc. The joint processing can use iterative or non-iterative inversion technique, where the iterative inversion technique may be a matching pursuit technique.
