It translates complex kinematic relations and vessel capabilities into an intuitive green-to-red threat surface directly within maritime environments.</p> <h2 id="key-features">Key Features</h2> <ul> <li> <p><strong>Fused Threat Model</strong>: Combines (1) sensor and weapon coverage, (2) vulnerability fields from blind zones and pose, and (3) CPA/TCPA-based threat estimates from kinematic features.</p> </li> <li> <p><strong>Real-Time Rendering</strong>: Custom Unity shaders render dynamic heatmaps directly on the simulation environment, updating in real time as vessel positions and intents evolve.</p> </li> <li> <p><strong>Integration</strong>: Fully integrated into NavySim and connected to intent recognition models. The heatmap encodes an agent&rsquo;s overall coverage and potential threats from surrounding vessels.</p> </li> <li> <p><strong>Decision Support</strong>: Gives decision-makers an intuitive understanding of evolving threats and the factors driving model outputs, supporting on-water and simulation-driven analysis.</p> </li> </ul> <h2 id="related-publications">Related Publications</h2> <ul> <li><strong>ThreatMap: A Framework for Enhancing Security Awareness and Decision-Making for Naval Agents</strong> — International Conference on Harbor, Maritime and Multimodal Logistic Modeling &amp; Simulation (HMS) 2024</li> <li><strong>NavySim: A Multi-Vessel Simulation and Analysis Engine for Naval Domains</strong> — IEEE CoG 2024 (integrated ThreatMap)</li> </ul>
