M3 Multibeam Sonar

The M3 Sonar is a 2D multibeam system with imaging and profiling capabilities. The M3 Sonar provides high-resolution and easy to interpret images by combining the rapid refresh rate of conventional multibeam sonar with image quality comparable to a single-beam sonar.

Multiple Applications

• Marine Engineering
• Shallow Water Bathymetric Surveying
• Site Inspection
• Environmental Monitoring
• Site Clearance
• Defence and Security

The Kongsberg Mesotech 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.

Four Pre-Defined 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
3. ROV Navigation: selects eIQ or imaging based on range
4. Profiling: narrow 3° beam used to generate a 3D point cloud
