Multibeam Forward Looking Sonar 

500m Long Detection Range | Collision Avoidance

100kHz Imaging Sonar for medium and large underwater vehicles

The UAC-FLS100 Imaging Sonar adopts multibeam imaging technology to generate acoustic images of suspended underwater targets and obstacles ahead of the sonar. All components are domestically manufactured, with fully self-controllable software and hardware. It meets the navigation assurance and target detection requirements of medium and large underwater vehicles.

FAQ  

Can I integrate FLS100 with my own AUV controller?

Yes, SDK and Ethernet protocol document are supplied for secondary development and system integration.

Custom depth rating is available on request.

It supports imaging mode (26° vertical FOV for detailed acoustic imaging) and collision avoidance mode (7° vertical FOV for obstacle alert). The vertical field of view is adjustable.

≥500m for -15dB target under favorable hydrological conditions. The actual detection distance will be affected by water quality, ambient noise and target strength.

It works on 18~36 VDC power supply with typical power consumption of 22W, and uses 100M / 1G adaptive Ethernet for data communication.
