Paper Abstract

This paper presents a figure-of-merit parameter for the scientific utility of multi-spectral linear array (MLA) instruments for civil remote sensing. The utility parameter is based on the observation that most analyses of earth resource satellite data are based on algorithms which combine measurements from two different spectral bands. Thus, the number of spectral band-pair choices available to the user of a given MLA instrument is offered as one very useful measure of the flexibility and overall utility of that particular instrument design. Also, the cost of a MLA instrument is a strong function of the number of linear arrays due to the requirement for additional electronics, larger optics, added thermal-controls and increased power requirements. However, research requirements currently project a need for a highly flexible instrument with a large number of spectral bands (arrays) for future earth remote sensing. Newly developing algorithms will undoubtedly continue to increase the number of desired spectral bands. Conversely, the bandwidth limitations of data-retrieval systems support an instrument design that has fewer linear arrays and changeable filters. This paper analyzes the Multi-band Selection Device capability mathematically, and provides a basis for a cost-benefit comparison of alternative multi-spectral instrument designs.
