MiniUAC-1402 2.5D Forward-looking Sonar
Software-Adjustable Vertical Field of View (FOV)
The MiniUAC-1402 forward-looking sonar is a distinctive imaging sonar with advanced vertical control capabilities.
Compared with conventional forward-looking sonars, the vertical field of view and vertical beam steering of the MiniUAC-1402 can be configured entirely through software. This enables the sonar to be used in specialized or innovative applications, such as measuring the height of underwater objects, stratified observation of targets at different water layers, and suppression of seabed and surface reflections.
The MiniUAC-1402 also features an automatic leveling function. By means of an integrated attitude sensor, the sonar can automatically adjust its vertical angle to compensate for beam displacement caused by platform motion, ensuring stable and accurate acoustic imaging.

Product Description
The MiniUAC-1402A 2.5D forward-looking sonar is a multibeam imaging sonar that provides forward-looking acoustic vision in both clear and turbid waters. It enables target detection and identification, obstacle avoidance, and hazard detection.
The sonar is characterized by its compact size, low weight, and low power consumption. Unlike conventional forward-looking sonars, the MiniUAC-1402A allows software-controlled adjustment of both the vertical steering angle and vertical beam width. This capability enables observation of objects at different depth layers, or within a selected portion of the water column, without the use of a mechanical pan-tilt unit. As a result, the sonar achieves an additional 0.5-dimensional vertical information acquisition, extending beyond traditional 2D imaging.
The center frequency of the MiniUAC-1402A is 1 MHz (Other frequencies are available upon request). The standard model supports a maximum operating depth of 300 m. For deeper operating depth requirements, please contact the manufacturer.
