Paper Abstract

A scheme for simplifying the design of CCD-based multispectral pushbroom scanners is presented. A new type of real-time signal processor permits registration of the images in the various spectral bands to ±0.1 pixel even though the system is mechanically aligned to only ±8 pixels. This permits design flexibility and cost reduction in the sensor optical system. The same signal processing can also correct for earth rotation skew and platform attitude errors at the same time, thereby simplifying the archiving and use of the data. An operational land observing system design that uses these ideas is described.
