摘要
对地面反射太阳光对远距离CCD探测系统的影响机理和太阳光的发散特性进行了研究,推导了目标物体在CCD探测系统入瞳面上照度的计算公式,建立了地面反射太阳光对远距离CCD探测系统影响的数学模型,并利用matlab软件对该数学模型进行仿真。通过分析,从理论上证明地面反射太阳光对CCD探测系统的影响是十分显著的。
Sun＇s rays reflected from the ground can influence satellite-borne photoelectric detecting systems. The influence mechanism of sun＇s rays on CCD detecting systems and the divergence of sun＇s rays have been studied. The illumination calculation formula of the object at the section of entrance pupil has been derived. A mathematical model of the influence that effected on the CCD detecting systems by the rays has been built up and simulated. In theory the influence of sun＇s rays reflected from the ground on CCD detecting systems has been confirmed.
