Acoustic equipment is the core sensor of underwater vehicle, it is the key equipment to guarantee autonomous navigation, autonomous obstacle avoidance, exploration environment and search target of underwater vehicle. Acoustic devices commonly used in underwater vehicles include acoustic Doppler log and various types of high-resolution imaging sonars (such as forward-looking sonar, down-looking sonar and side-view sonar). Among them, each use of sonar and a variety of ways to achieve technology.

The Main Function

1. Four-dimensional modeling of submarine, sea surface, target and aircraft body (3D shape + material)
2. Dimensional six-degree-of-freedom (DOF) modeling of the motion of the vehicle body.
3. Real-time response to user input, real-time generation and display of high-fidelity acoustic system original echo data and imaging data. The resulting data is not only highly similar to the actual acoustic device in terms of display performance, but is also statistically very similar to the actual acoustic measurements.
4. To meet the acoustic Doppler log, front, bottom, side view and other mainstream acoustic equipment simulation requirements.According to the user's requirements, the specified model of the device simulation. 
5. Has a semi-physical simulation capabilities, through the docking array in the air directly to the acoustic system for testing.
6. Standard data input and output interface. XTF and other standard acoustic data formats can be generated according to user requirements, and users can directly import CARIS, HYPACK and other international common acoustic data post-processing software.
