摘要：
This paper presents a simple solution to the problem of estimating effective source signatures for each air gun in an array. It is assumed that each individual source in the array gives the field of a spherical expanding wave in a homogeneous medium. Then, by linear least-squares inversion the time functions of the body-force distribution in the equation of motion governing the wave propagation are estimated. The inversion strategy is formulated in the frequency domain, giving one independent estimation problem for each frequency. Two numerical examples using synthetic data are presented. -from Author
