ThreatMap: Maritime Situational Awareness
ThreatMap dynamic risk heatmap in naval simulation (HMS 2024 / M.S. Thesis)ThreatMap: Maritime Situational Awareness (2021–2023) is an interpretable, real-time spatial risk visualization framework developed as part of Md Abu Sayed’s M.S. thesis research at the University of Nevada, Reno, and published at HMS 2024. It translates complex kinematic relations and vessel capabilities into an intuitive green-to-red threat surface directly within maritime environments.
Key Features
Fused Threat Model: Combines (1) sensor and weapon coverage, (2) vulnerability fields from blind zones and pose, and (3) CPA/TCPA-based threat estimates from kinematic features.
Real-Time Rendering: Custom Unity shaders render dynamic heatmaps directly on the simulation environment, updating in real time as vessel positions and intents evolve.
Integration: Fully integrated into NavySim and connected to intent recognition models. The heatmap encodes an agent’s overall coverage and potential threats from surrounding vessels.
Decision Support: Gives decision-makers an intuitive understanding of evolving threats and the factors driving model outputs, supporting on-water and simulation-driven analysis.
