Study on Distribution Characteristics of Local Atmospheric in Homogeneities Excited by Combined Array Coherent Sound Sources
As mechanical waves with energy, acoustic waves interact with atmospheric physical parameters during propagation, disturbing the spatial and temporal distribution characteristics of atmospheric turbulence. Based on the wave equation and superposition principle of sound waves, combined with the relationship between atmospheric refractive index and atmospheric physical parameters, this paper analyzes the excitation of a single point array sound source and five different types of combined array coherent sound source models through theoretical modeling and numerical simulation. Artificial refractive index inhomogeneity distribution. The results show that the distribution characteristics of the inhomogeneous body excited by the combined array sound source on the local space plane are affected by the number and distribution position of the array sound source. The larger the order of magnitude, the stronger the ups and downs. This paper provides a new idea for generating or suppressing turbulent effects, and the numerical calculation results can provide a basis for selecting appropriate sound source models in optical engineering applications.
