Abstract
A method for complex source signature estimation for offshore acquisition is presented. Although the wave‐propagation velocity in the water is assumed to be known, no assumptions about the material properties underwater are made. The inputs to the algorithm are the pressure field measured along an end of spread streamer cable, the coordinates of the sources, and the depth of the cable. The output is the complex spectrum of each individual source in the source array. This article discusses the physical interpretation of the equations. It is shown that the estimated wavelets depend on the direct field only. The sensitivities of the method are also discussed. Application of the algorithm on generated and measured data is presented.
