METHOD FOR REDUCING INLINE DIRECTIVITY OF AIR-GUN SOURCE SIGNATURE BY OPTIMIZING SPATIAL DISTRIBUTION OF AIR-GUNS

摘要

A method for reducing inline directivity of an air-gun source signature by optimizing spatial distribution of air-guns is provided according to the present application, which relates to a field of design and optimization of an air-gun source. An evaluation standard in the air-gun distribution in an air-gun array direction is proposed. By a combination optimization along both the inline and depth directions, a design scheme having evidently broader effective bandwidth and effective take-off angle width than a design scheme of a conventional source is obtained, with which the directivity of the air-gun source signature can be reduced.
