摘要
本文在研究45°扫描镜地面像元变化过程的基础上,对45°镜多元并扫像元变化特征和扫描轨迹进行了分析,给出了扫描轨迹计算式。讨论了像旋对地面分辨率的影响,分析了系统是否存在漏扫的条件,得出了不漏扫遥感器扫描参数需满足的条件。
Based on the study of imaging changes of a 45° rotating scanning mirror on the ground, the imaging characteristics and scanning traces of the 45° rotating scanning mirror are analyzed and the calculating method of the scanning trace on the ground is given. The influence of image rotation on the ground resolution is discussed, the missing scanning condition of the system is analyzed and the condition which the remote sensor should meet to avoid missing scanning is provided.
