Real-time Underwater Channel Simulation
The video shows the application of KiRAT for SONAR applications. Several send and receive hydrophones can be placed in an underwater environement with adjustment possibilities, such as sound velocity profiles (depth dependent). In addition, wind speed and direction can be adjusted (both is fed into a statical model for creating a time and location dependent water surface and corresponding noise). Furthermore, several moving target can be simulated. The channel simulation is based on a restricted 3D ray tracing scheme, that allows freqeuency dependant ray parameters (e.g. reflection and attenuation).
