Intelligent Surface Threat Identification System (ISTIS) IEEE Aerospace Conference 2007 Presented by: Robert Richards, Ph. D. Richards@Stottler. Henke. com www. stottlerhenke. com

Objectives • Improve Littoral ID Process, quality, and efficiency – Better ID estimations from available data – Sooner ID determinations – Prevention of ID “Surprises” – Better use of scarce ID resources • Investigate littoral, surface ID techniques • Implement in the Intelligent Surface Threat ID System (ISTIS)

Related Projects • • • Intelligent Identification Software Module (IISM) LCS Undersea Threat Assessment TAO ITS and ITS authoring tool GRTS TAO ITS Navy Tactics Representation and Execution System (TRES) • Visual Intelligent Behavior Authoring (Sim. Bionic) • Advanced Early Warning Real-Time Advisory System (AEW/RTAS)

Motivation: Current Identification Problems • Wide variation in ID abilities • Knowing whose-who even after ID information received • Track Split/Merge • Maintaining Competing Hypotheses for a track • Classified Automatic Track ID Problems • Remembering Track History (both short and long-term) • Analyzing behavior/correlations • Correlating new tracks with previous tracks • Knowing/Executing Optimal ID Procedures • Quickly Assessing Threat

Architecture

AI Techniques • • • Truth Maintenance Case-Based Reasoning Behavior Transition Networks (BTNs) Fuzzy Logic Pattern Recognition/Learning Constraint-Based Planning, Scheduling, and Resource Optimization • Knowledge Elicitation / Cognitive Task Analysis • Expert Systems

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)

ISTIS Capabilities (More & Re-stated) • Merge-Split Processing for Radar Merges and Track Fades and Reasoning through Multiple Hypotheses • Maneuver Correlation Detection • Surface ID Processing, Fusion, and Behavior Analysis • Action Recommendation based on Heuristics • Route Planning to ID a Set of Contacts and/or Search an Area • Ability of Tactical Personnel to Edit and Change ID, Alerting, and Recommendation

Demonstration • Strait of Malacca • Alerts: Leaving commercial lanes / intercepting • Merge-Split: automatic reasoning backward and forward • Multiple hypothesis / Hierarchical reasoning • Intercept/formation maneuver correlations • Heading and UAV recommendations • Immediate Threat alert • Demo video

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
