Paper Abstract

The use of solid-state detector arrays which operate in a pushbroom scan mode for remote sensing of the Earth's resources and environment has received increased attention in the last several years. The potential for improved radiometric sensitivity, geometrical accuracy and signal processing permit consideration of new levels of sensor performance in the areas of spatial resolution, spectral resolution, mapping accuracy, and improved system throughput of data products. These benefits depend on the ability to manufacture and accurately align thousands of detectors into a multispectral focal plane. Two key performance goals are to achieve: (1) radiometric calibration to 0.5% precision detector-to-detector over a dynamic range of 1000:1; and (2) geometric alignment to place the detector elements to within 0.1 resolution element of their desired perfect positions. System cost (including the ground segment) and complexity should be traded against these goals. Science experiments continue to be needed to establish the tolerances on these goals.
