The objective of this Phase I proposal is evaluate battlespace geolocation correlation opportunities that may be obtained by fusing measurements from Ground Moving Target Indicator (GMTI) and Signals Intelligence (SIGINT) collections. These opportunities include (1) improving geolocation accuracy at the processing level using individual sensor measurements from dissimilar collection systems and (2) improving sensor tasking throughput by leveraging serendipitous and fully cooperative tasking opportunities. Both a real-time capability that examines live data feeds and reach-back capability that examines previously recorded events will be investigated. Improvements in ISR system performance, timeliness, and capability. Reduced sensor resource requirements
