Abstract
Method for estimating source signature of a marine seismic source array in a naturally band-limited subsurface region, for designature processing of resulting seismic data. Direct arrivals identified in the streamer receivers' records () provide a far-field estimate of the source signature, provided that the subsurface naturally limits frequencies to below the first notch frequency in the amplitude response of the seismic streamer receiver array. Processing of the direct arrivals may include move out or alignment correction (), signal enhancement (), summing of direct arrival traces over all offsets (), windowing or tapering of direct arrivals (), and deterministic corrections to the combined direct arrivals to compensate for ghosting and streamer array effects ().
