Study on the Controlled Atmospheric Refractivity Fluctuation Impairing the Imaging Quality of the Heterodyne Detection Lidar
Based on the principle of heterodyne detection and the array-distributed atmospheric refractivity fluctuation by a coherent acoustic,the theoretical feasibility of coherent acoustic waves affecting lidar imaging by changing the additional phase is analyzed,and the theoretical model of changing the additional phase is established.According to the theoretical model,the echo phase of the imaging radar is simulated and the adopted acoustic array.A scaling experiment is designed to verify the engineering feasibility of the controlled atmospheric refractivity fluctuation impairing the imaging quality of the heterodyne detection lidar by coherent acoustic wave effects on transmission-coherent laser imaging path.The results of this paper have important theoretical significance for the development of new methods and technologies in the field of lidar interference.
