        Abstract: In order to explore the influence of complex atmospheric environment on radio wave propagation, the experiment of coherent acoustic wave disturbing atmosphere on radio wave propagation was set up, which verified the feasibility of acoustic wave disturbing atmosphere. By combined parabolic algorithm and inferred the theory of coherent sound waves disturbed the atmosphere, the propagation loss of a large-scale controllable array disturbance in an evaporative waveguide was simulated. The results show that coherent acoustic wave disturbs the evaporator waveguide and causes obvious propagation loss variation. It provides an important theoretical basis for quantitative changes in the electromagnetic characteristics of atmospheric environment, and is of great significance for solving the interference caused by 5G in the face of evaporation waveguide and ultra-long-range visual range propagation, etc.
