MiniUAC-1310/1311    Deep-Sea Forward-looking Sonar

600m / 11000m Extreme Working Depths

The MiniUAC-1310 and MiniUAC-1311 deep-sea forward-looking sonars are designed for operations requiring extreme working depths. The MiniUAC-1310 supports a maximum depth of 6,000 m, while the MiniUAC-1311 reaches a full ocean depth of 11,000 m. Both models have been successfully validated on multiple deep-sea vehicles and deployed in challenging environments, including the Mariana Trench. They are suitable for various manned or unmanned deep-sea vehicles and deep-sea workstations.

The MiniUAC-1310A is a 2D multi-beam imaging sonar capable of providing forward acoustic vision in both clear and turbid waters. It enables target detection, recognition, collision avoidance, and obstacle surveying. Key features include small size, lightweight design, low power consumption, and fully domestically-produced, controllable components. Single-frequency and dual-frequency options are available, with multiple operating frequencies customizable to user requirements.
