Kongsberg M3 Shallow Water Multibeam Sonar
Kongsberg Mesotech’s M3 Sonar is a multibeam system with both imaging and profiling capabilites. The M3 Sonar 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.
M3 SONAR SOFTWARE
The M3 Sonar software was developed specifically for the M3 Sonar to manage communications with the head and operate all beamforming and image processing.
There are four predefined operating modes:
1. Imaging: Long-range navigation with high-speed update rate.
2. Enhanced Image Quality (eIQ): Greatest image quality (0.95° angular resolution) from a short range with a slower update rate.
3. ROV Navigation: Selects eIQ or imaging based on range.
4. Profiling: Narrow 3° beam used to generate a 3D point cloud.
