This Phase II SBIR proposal addresses the problem of testing and applying the clutter suppression techniques developed during the Phase I project to space based infrared and visible spectral and hyperspectral imaging systems. The goal of the Phase II effort is to implement clutter mitigation algorithms which can be applied to a variety of space based systems such as WARFIGHTER and SBIRS, and unmanned tactical remote sensing systems, which require efficient and effective real-time clutter characterization and suppression. Real-time algorithms tests will be carried out for these systems using realistic system hardware configurations. This second phase SBIR proposal builds on the innovative techniques devised during the first phase program for effective spatial and spectral clutter characterization and rejection. We have demonstrated several approaches to clutter characterization and rejection which are applicable to space-borne spectral and hyperspectral sensors and will test these algorithms in real time processors simulating WARFIGHTER/MIGHTYSAT II.1 and other systems. Three test levels are proposed: brassboard tests using the thew FTHSI hyperspectral sensor testbed developed by Kestrel Corp., flight tests simulating BTH operations or SBIRS-HI, airborne reconnaissance systems, and certain types of seeker systems, and tests using the Mightysat II.I space prototype data system which wll be applied to WARFIGHTER.
