Passive Sonar Simulator Vulnerability Assessment

This article discusses the need for security and assessment in deploying ships in maritime regions, with a focus on the Indian Ocean. It explores vulnerability assessment, which involves studying a ship’s vulnerability to detection using the sonar equation. The survivability of naval ships is also examined, considering susceptibility, vulnerability, and recoverability. The challenges of maritime threat detection, such as complex environments and limited research, are highlighted. The article suggests using existing technologies and statistical models like Hidden Markov Models, Conditional Random Fields, and Markov Logic Networks for vulnerability calculations. It emphasizes the importance of mapping ambient noise and radiated ship noise and addresses challenges related to receiver characteristics and advanced technologies like infrared homing missiles. Applications of the assessment include combat management systems, weapon control, and target identification. The article proposes future steps like implementing 3-D vulnerability maps, automating data analysis, using cognitive models, and developing efficient probabilistic models, including machine learning approaches.
