摘要
分析了不同测图比例尺对测图卫星空间分辨率和交会角的要求和在使用三线阵延时积分电荷耦合器件(TDICCD)技术进行立体测绘时,由于地球自转导致的残留角将使测图卫星系统的调制传递函数(MTF)劣化,提出了减小影响图像质量方法的建议。
This paper analyses the requirements different mapping scale for different space revolutions and crossed angle of mapping satellite and that when using three-linear TDICCD technology to stereo mapping, the earth rotation causes remain yaw angle that makes MTF of the mapping satellite system descended. Finally it puts forward methods to improve image quality.
