High Efficiency Conical Scanner For Earth Resources Applications
Jerry C. Bates, Henry J. Dumas · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 1974
Earth resource scientists are demanding greater classification capability from remote sensing instruments. The trend is for more spectral bands with finer spectral resolution and improved spatial resolution. These requirements greatly impact instrument design, particularly since data bandwidth is increased proportionally. An instrument concept is described which, from a spacecraft platform, provides seven band coverage, 30 meter ground resolution and 100 nautical miles swath width. Its 80% scan efficiency yields a near minimum data transmission band-width.
