摘　　要：在应用CCD探测器的空间相机系统中,CCD信号处理电路与CCD探测器的匹配性至关重要,决定了整个相机系统的性能指标,因此在CCD信号处理电路设计完成后,需要对设计的匹配性进行分析。首先,介绍了空间相机系统CCD信号处理电路的典型结构;然后,提出了基于动态范围的匹配性分析方法;最后,应用该分析方法对某空间相机系统的CCD信号处理电路设计进行了匹配性分析,发现了电路设计中存在的不匹配环节,为优化电路设计提供了依据和建议。In the system of space camera using CCD as the sensor, the matching design of signal processing circuit with the CCD sensor is crucial, and the performance of whole space camera is determined, so the matching analysis should be done after the design of CCD signal processing circuit is finished. Firstly, the typical structure of CCD signal processing circuit in space camera is introduced; then, the analyzing method of matching is proposed based on dynamic range; finally, this method is used in one space camera proiect and found some not suitable design in the circuit, the basis and suggestion of optimization in circuit design is provided.
