幅宽是影响高分辨率光学遥感卫星应用的重要指标。本文分析了国际上高分辨率光学遥感卫星宽幅成像的主要途径,介绍了多CCD内视场拼接、多相机外视场拼接、敏捷成像、多星组网等主流宽幅成像方式及其数据处理的技术特点,同时分析了相机垂轨摆扫成像、大面阵相机敏捷拼幅成像等新型星载宽幅影像获取方式,有助于系统地了解高分辨率光学遥感卫星宽幅成像技术进展,对于展望其发展趋势具有一定的参考作用。
The width is an important index that affects the application of high resolution optical remote sensing satellites. This paper analyzes the main ways of wide-area imaging of high-resolution optical remote sensing satellites in the world, and introduces the mainstream wide-format imaging methods such as multi-CCD internal field splicing, multi-camera external field splicing, agile imaging, The technical characteristics of the new satellite remote sensing satellite image acquisition system are also analyzed. The acquisition of new spaceborne wide-angle image acquisition methods, such as camera vertical-sweep pendulum imaging and large-area camera agility spellcasting, are also analyzed to help systematically understand the progress of high-resolution optical remote sensing satellite wide- , For the prospects of its development trend has a certain reference.
