摘要： 在卫星遥感中利用广角线阵CCD相机对地球资源信息进行“粗查”,并同时利用高分辨率CCD 相机进行“详查”的遥感器组合是一种可行的方案。文中介绍广角CCD 相机的研制及利用小型无人机进行机载试验的结果。在方案设计中主要讨论几何分辨率和辐射分辨率两项指标,也兼顾讨论诸如扫掠宽度和覆盖周期等问题。为获得好的机载试验效果将相机安装在双轴稳定平台上。

Abstract: In satellite remote sensing,using wide field linear array CCD ca-mera and high resolution CCD camera as a combination of sensors is a feasibleapproach.The former is used for coarse observation oi the earth resources in-formation and the later for fine observation.The development of the wide fieldCCD camera for satellite use and its air-borne test result on board small sizepilotless aircraft are presented.In system design,main consideration is givento geometric resolution and radiation resolution.The problem of items,suchas swath and recovery period etc,are also discussed.The camera is installed ona two axes stabilization platform to obtain good air-borne test result.
