【摘要】 将光电成像系统中的光学系统和探测器视为线性系统,应用匹配滤波和等效平方带宽理论,综合考虑了系统的信噪比和带宽,建立了基于信噪比通道宽度的系统性能评价模型。利用评价模型进行计算机仿真。根据仿真结果分析,得出了光学系统与探测器的匹配特性和最佳匹配条件。
【Abstract】 By extending matched filters and equivalent square bandwidth theory to photoelectric imaging system in which the optical system and detector are looked as linear systems. The model of system performance evaluation based on signal to noise ratio bandwidth is built. Signal to noise ratio bandwidth-based computer simulation results are given. According to simulation results, the general matching features and ideal matching condition between optical system and CCD detector are obtained.
