    The Shark-S455M Embedded Multi-beam Side Scan Sonar is specifically designed for USVs (Unmanned Surface Vehicles), ROVs (Remotely Operated Vehicles), AUVs (Autonomous Underwater Vehicles), UUVs (Unmanned Underwater Vehicles), and other embedded platforms. The system’s towfish incorporates five beams per side, ensuring high-speed operation and high-resolution imaging. It features an advanced dynamic digital focusing algorithm that significantly enhances along-track resolution at mid-range and near-range distances. The ability to scan at high speed greatly improves survey efficiency. Additionally, the system supports a low-speed, dual-frequency scanning mode that can be switched in real time, achieving an optimal combination of high resolution and long-range coverage.

    The system consists of two transducer arrays, an electronic unit, and OTech’s proprietary sonar software. The electronic unit comes in two versions: a built-in non-sealed type and an external sealed type. Designed for ultra-low power consumption, the system operates on a DC supply of 18–36V.

    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. The software’s basic parameters can be controlled remotely. It can output raw data in real time for AI-based automatic target recognition development, while simultaneously saving data in XTF format for processing with third-party software. SDK support is available for secondary development.

    Key Features

    • Dynamic digital focusing algorithm, which significantly enhances resolution
    • 5 beams per side (10 total), delivering high-resolution imaging at speeds up to 10 knots
    • Command-based remote control of operations and parameter settings
    • Real-time raw data logging and output for auto target recognition development
    • OTech’s multifunctional software offers free periodic upgrades and updates.
    • Full-coverage real-time mosaicking and imaging with SDK support.
