Abstract"Tracking midcourse objects for SBIRS Low is a truly significant anddifficult scientific problem that must be solved to provide aconsistent set of tracks to discrimination. For the space based IRsensors, the resolution is limited due to the geometry and distancefrom the satellite to the targets. Viewed on the focal plane for asingle IRsensor, the threats appear to transition from an unresolved phaseinvolving pixelclusters into a mostly resolved phase through a possibly longpartiallyunresolved phase. What is more, threats can appear in differentresolution phases at the same time for different sensors.These resolution problems make multi-sensor tracking most difficult.A key observation in the proposed solution is that what mayappear to be a large cluster from one sensor's view may be multipleresolved objects or small clusters from another's sensor's view.Thus, the proposed approach to supplying discrimination with a set oftracksconsisting of resolved objects or small clusters is to use the fusionnode information to assist signal processing with breaking largerclusters into a number of smaller clusters or resolved objectsconsistentwith the need of multi-sensor tracking. State-of-the-art multi-sensor missile tracking system for SBIRS-Low and other IR tracking systems. Advance methodologies to integrate tracking and signal processing to improve overall performance of developed missile defense systems. High potential tomodernize the track
