ISTIS Capabilities• Intelligent Tactical Memory:
Track attributes (position, velocity, ID information, History)
Associate previous tracks with new track information.
Complete track history (track merge or ID swap) Past Relevant Tracks/Patterns used to
recommend/warn Definable ID, Threat Assessment, & Notification
Criteria Intelligent Track History Analysis
(position/velocity/proximity/interactions/behavior correlations) to estimate associations & hostile intentions
Multiple Competing Hypotheses for ID (type/owner country) with Hierarchy of possible ID values (type, color/country)

Conclusion• ISTIS is an AI system that improves the Littoral ID
Process, quality, and efficiency by– Better ID estimations from available data
• Tracking ambiguous signals• storing and handling past target data
– Sooner ID determinations– Prevention of ID “Surprises”
• assessing threat levels & notifying users of alert conditions
– Better use of scarce ID resources• filtering out insane data• keeping track of multiple track hypotheses based on the fusion of
evidence from multiple sources
• Capable today and continuing to be enhanced• Lockheed Martin (a LCS Builder) is partner• Interested in other potential users or partners
