According to the imaging principle of laser active imaging system and linear system theory,the MTF model of laser active imaging system for moving targets is established and simulated by using Matlab based on the general MTF model of electro-optical imaging system,and the MTF model considers the influence of atmosphere turbulence and motion on system imaging performance.Combined with the simulation results,the main factors that limit the system MTF and the effect of target motion are analyzed,which lays a theoretical foundation for the future evaluation and optimization of the system performance.
