Sonar simulation for the Action Speed Tactical Trainer at KNM Tordenskjold
MetadataShow full item record
This report describes a sonar simulation module planned implemented into Kongsberg Defence and Aerospace’s Action Speed Tactical Trainer. A land-based and modular training facility for frigate crew members. The sonar simulation module generates sonar audio, echoes and tracks based on an acoustic propagation model called Lybin. Lybin is the property of the Norwegian Navy. The acoustic modelling includes depth-dependent sound speed profiles, high-resolution topography and varying sonar settings. Both real targets and terrain features generate echoes. Methods of running the model in real-time are proposed.
