| 摘 要： | 为了研究振动和级数对星载TDI CCD成像质量的影响,模拟了发生振动时不同TDI CCD级数的图像,并采用像移计算MTF方法对成像质量进行评价.结果表明:发生振动时,TDI CCD级数变化对成像质量会造成影响,成像质量随着TDI CCD级数的增加而下降;TDI CCD级数的选择应结合卫星姿态控制精度、发生星颤时造成像移的大小等因素综合确定.

| Abstract: | In order to study the influence of vibration and series on imaging quality of satellite borne TDI CCD,this paper simulates images of different TDI CCD series during vibration and evaluates the imaging quality by calculating MTF through image motion.The results show that change of TDI CCD series affects the imaging quality during vibration,imaging quality decreases with the increase of TDI CCD series,and TDI CCD series should be selected combing factors such as controlling accuracy of satellite posture and image motion degree during satellite chattering. |
