METHOD AND SYSTEM FOR SCANNING OF A FOCAL PLANE ARRAY DURING EARTH OBSERVATION IMAGING

摘要

A method includes providing a body, an actuator coupled to the body, a stage coupled to the actuator, an image sensor coupled to the stage, a first staring focal plane array that is located at a first location, and a second staring focal plane array that is located at a second location that is offset from the first location in two dimensions. The method also includes determining a velocity of the body, causing the actuator to backscan the stage in one or more directions at a drive velocity corresponding to the velocity of the body, causing the first staring focal plane array to capture a first strip of images of a target, and causing the second staring focal plane array to capture a second strip of images of the target. The second strip of images is offset from the first strip of images in the two dimensions.
