A high-resolution multispectral scanner for earth observation
Abstract
Design of a scanning system for earth observation in the visible, near infrared and thermal infrared spectral ranges is discussed. The scanner, which has a spatial resolution of 20 m and a scanning field of plus or minus 17 deg (plus or minus 120 km), is a static system, involving the 'push-broom' technique instead of a sweep system. Selection of a telescope for the scanner, performance of the optical system, and problems associated with detector noise are reviewed; the satellite for which the scanning system was developed is also described
