MTF modeling and simulation of laser active imaging system for moving target

根据激光主动成像系统的成像原理和线性系统理论,在光电成像系统通用MTF模型的基础上,考虑了大气湍流和运动对系统成像性能的影响,建立了针对运动目标的激光主动成像系统MTF模型,并利用Matlab进行了仿真研究。结合具体的仿真结果,分析了限制系统MTF的主要因素以及目标运动的影响,为后续进行系统性能的评估和优化奠定了理论基础。

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.
