| 摘 要： | 对光电系统成像过程进行了建模仿真研究,采用光线跟踪法建立了成像过程的光线跟踪模型;根据线性滤波理论,对系统的各组成单元的调制传递函数进行分析,给出整个系统的传递函数,建立了成像过程的传递函数模型;结合光线跟踪与调制传递函数模型,建立了光电系统对空间目标成像仿真物理模型,给出了仿真流程;最后,进行了成像仿真,结果给出了目标在像面上的灰度分布曲线及仿真图像,验证系统理论传递函数,证明了模型的合理性.

| Abstract: | The imaging process of the electro-optical system is studied,and the lay tracking modeling of this process is established using the lay tracking theory.Based on the linearity strain-wave theory,the MTF of every component unit in the imaging system is analyzed and presented,and the MTF model is also established.Combining the lay tracking model with the MTF model,a physical model of the Electro-Optical system for space target surveillance is established,and the simulation flow is presented.At last,the simulat... |
