A novel idea of purposefully affecting radio wave propagation by coherent acoustic source-induced atmospheric refractivity fluctuation

摘要

The mechanism generating the array-distributed atmospheric refractivity fluctuation by a coherent acoustic source is analyzed. The theoretical model is established, which is used to quantifiably analyze the array structure of the artificial dielectric irregularities. It is qualitatively validated that the array-distributed artificial dielectric irregularities really exist and that the array structure of the artificial dielectric irregularities and the scattering effect of the artificial dielectric irregularities on a radio wave can be controlled by adjusting and selecting the optimized parameters of the transmitted acoustic wave and the adopted acoustic antenna array. It can be concluded that the array-distributed artificial dielectric irregularities can be used to purposefully affect radio wave propagation. After radio acoustic sounding system, the idea of this paper is a novel development in the field of the tropospheric atmospheric refractivity artificial abnormality technique and its applications.
