An Algorithm for Submarine Passive Sonar Simulator

THE JOURNAL OF THE ACOUSTICAL SOCIETY OF KOREA, 2013
Actual maritime exercise for improving the capability of submarine sonar operator leads to a lot of cost and constraints. Sonar simulator maximizes the capability of sonar operator and training effect by solving these problems and simulating a realistic battlefield environment.
