Types of simulated sonar devices:

• Mechanical scanning imaging sonar (MSIS)
• Forward-looking sonar (FLS)

Packages

The imaging sonar simulation is split into five main packages, as follows:

• simulation/normal_depth_map: samples each OSG frame and computes the sonar rendering parameters during rasterization pipeline on GPU: echo intensity and pulse distance;
• simulation/gpu_sonar_simulation: decodes the sonar rendering parameters into simulated sonar data;
• simulation/orogen/imaging_sonar_simulation: simulates the operation of MSIS and FLS sensors; controls the virtual sonar device in the underwater scene; handles sonar properties; and provides I/O ports to interact with other Rock components.
• simulation/uwmodels: contains the underwater scenarios and 3D models;
• simulation/examples: contains scripts to run the imaging sonar simulations.
