Abstract
A technology for ultra-wide circular scanning imaging by an optical satellite is provided. Calculating an angle θbetween the outermost field of view of an area array camera () and an earth-pointed axis (q) of a satellite () according to the width W required for ground imaging coverage in a direction perpendicular to the flight direction (b) of the satellite () and according to the height h of the orbit of the satellite (); installing the area array camera () on a side surface of the satellite () according to the angle θ; calculating the maximum rotation angle ωallowed by the satellite () according to the minimum exposure time T of a detector of the satellite () and the worst ground pixel resolution r of the satellite (); selecting a rotation speed ω of the satellite () that is less than ω, and setting the rotation speed ω to be the rotation speed relative to the ground.
