摘　　要：为了探究复杂大气环境对电波传播产生的影响,设置相干声波扰动大气影响电波传播的实验,验证了声波扰动大气的可行性;将相干声波扰动大气理论进行合理推演,结合抛物型算法,仿真了大规模可控声阵列扰动的蒸发波导下的电波传播损耗,结果表明相干声波扰动蒸发波导引起明显的传播损耗变化.本文研究为定量改变大气环境电磁特性提供了重要的理论基础,对解决5G面临蒸发波导带来的干扰、超远程视距传播等都有重要意义.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.
