Shark-S450S Single-Frequency Side Scan Sonar is a compact, lightweight, and portable sonar with ultra-low power consumption. It features 450kHz CHIRP signal processing technology, providing a range of 150 meters per side to ensure wide coverage. With a 0.3° horizontal beamwidth, it delivers high-resolution imaging.
The system’s core components include a pressure-resistant towfish, a high-strength Kevlar cable, a waterproof deck unit, and proprietary OTech sonar software. The towfish is engineered with a robust and durable structure while maintaining compact and lightweight. It supports single-operator deployment and retrieval and can be configured for towed, hull-mounted, or side-mounted operation. The optimized hydrodynamic profile ensures stable towing performance under varying conditions. The system is designed for ultra-low power consumption and can operate on AC power or via an inverter connected to a battery supply. The system has an ultra-low power consumption design and supports both AC power supply and battery inverter power.
The proprietary OTech software includes features such as real-time image mosaicking, sonar image display, survey line planning and navigation, track tracking and coverage display, data recording and playback, target management and export, and multi-window sensor information display. The sonar image adaptive equalization technology ensures consistent display quality for both near and far images. With minimal parameter settings and a user-friendly interface, the software is easy to operate. It supports output in standard XTF format, enabling processing in third-party software.
