Improved air gun array sound wave transmission modeling method

The invention discloses an improved air gun array sound wave transmission modeling method, which considers the influence of air gun pulse phase shifts at different positions and air guns with different capacities on transmission directionality, combines an improved sound transmission model and an accurate Van der Waals air gun wavelet model in a frequency domain, performs inverse Fourier transform, performs sound pressure superposition on all air guns to realize air gun array sound pressure transmission modeling, and quantitatively evaluates the finite duration and time-varying amplitude sound pressure signals of the air gun array by using a zero-peak sound pressure level and a sound exposure level. The method not only considers the influence of the directivity of the air gun array model, but also considers the influence of marine environment influence factors on sound transmission and the influence of phase shift differences of different air gun capacities and air gun pulses at different positions on the sou
