The Shark-S75T Tri-Frequency Side Scan Sonar is a versatile multi-frequency sonar designed for deep-water surveying. It operates at three frequencies: 75 kHz, 225 kHz, and 750 kHz, allowing for both low-frequency and high-frequency combinations. Equipped with standard Chirp signal processing technology, it enables wide swath coverage while ensuring ultra-high-resolution imaging.
The system consists of a high-pressure resistant stainless steel towfish, a high-strength armored coaxial cable, a waterproof deck unit, and proprietary OTech sonar software. The towfish is engineered for reliability and durability, with optional magnetometer interface and underwater positioning mounting structure. It supports multiple deployment methods, including towing, hull mounting, and side-mount installation. The underwater overload protection design provides effective impact protection, enhancing the towfish's safety during underwater operations.
The proprietary OTech software combines ease of use with powerful functionality, offering features such as real-time image mosaic stitching, sonar image waterfall 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 software utilizes adaptive equalization processing technology to ensure consistent image quality across both near and far ranges. With minimal parameter settings and a user-friendly UI design, it is straightforward to operate. It supports output in the standard XTF format, compatible with third-party post-processing software. The software can be customized to meet specific requirements. The enhanced version provides real-time output of multiple raw data formats, enabling the development of AI-based automatic target recognition features.
