System 5900

Klein Marine Systems’ flagship military side scan sonar is the Klein 5900.

The Klein 5900 is a robust, field-proven sonar system that delivers near-Synthetic Aperture Sonar (SAS) performance for defense, survey, and offshore operations. By integrating high-speed, high-resolution sonar technology with embedded electronics and artificial intelligence software, the Klein 5900 provides unmatched underwater imaging, target detection and operational efficiency.

Key Capabilities

• High-speed, high-resolution survey: Achieve 3.2 cm across-track resolution and 0.07° along-track resolution at survey speeds up to 12 knots, delivering ultra-high-resolution data rapidly with near-SAS performance.

• 100% bottom coverage: Nadir gap filler sonar ensures complete seafloor coverage at high resolution, reducing survey time and eliminating repeat missions.

• Integrated bathymetry: Co-registered bathymetry adds topographic detail for real-time decision-making and improved data quality.

• Motion-tolerant design: Operate effectively in challenging sea states with the 5900’s inherent motion-tolerant engineering.

• Automatic Target Recognition (ATR): Built-in ATR powered by Spectral AI software enables rapid, in-field detection and classification of mines, unexploded ordnance (UXO), and other underwater objects.

Operational Advantages

• Mine Countermeasure (MCM) operations: Conduct efficient surveys with near-SAS resolution across wide operating windows, cutting MCM campaign time by weeks.

• Surveillance missions: Perform rapid, high-resolution seafloor surveys with 100% bottom coverage using a system designed for unpredictable environments.

• Geophysical and UXO surveys: Support offshore renewable energy projects with a sonar system that exceeds today’s industry specifications and anticipates future requirements.
