Kongsberg M3 HF Imaging and Profiling Multibeam Sonar

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 Detection of small objects out to 150 meters combined with a 120° to 140° field of view allows the operator to see the complete underwater picture in real-time.

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.

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.
