Kongsberg M3 Sonar® HF with sound velocity sensor

Multimode multibeam sonar 922-2036000

Kongsberg Discovery’s M3 Sonar HF is a multibeam system with both

imaging and profiling capabilites. The M3 Sonar HF provides high-resolution

and easy-to-interpret images by combining the rapid refresh rate of a

conventional multibeam sonar with image quality comparable to a single beam sonar.

The complete package

This model includes an integrated Sound Velocity Sensor. The embedded processor inside

this sensor handles all signal processing, timing, and math, allowing the device to provide

continuous realtime sound velocity measurements.

Don’t miss a thing

Detection of small objects out to 100 meters combined with up to a 140° field of view

allows the operator to see the complete underwater picture in real-time. The M3 Sonar HF

provides high-resolution images at short range, reducing the time it takes to search for and

locate targets.

Multiple installation options

The M3 Sonar HF is suitable for a wide range of vehicles from ROVs to USVs and ASVs.

When using a surface vessel, you can easily deploy the M3 Sonar HF on a pole mount. This

sonar can also be tripod mounted.

User-friendly software

The operating software was developed specifically for the M3 Sonar HF to manage

communications with the head and operate all beamforming and image processing. The

predefined imaging modes present distortion-free images at a high update rate. For an

alternative data visualization, the provided profiling modes generate a 3D point cloud.
