The Shark-S100D dual-frequency side-scan sonar is a versatile system suitable for both shallow and deep-water surveys. It features dual-frequency synchronous transmission/reception (100 kHz and 450 kHz) and Chirp frequency modulation processing technology, enabling both wide coverage swaths and high-resolution imaging.
The system includes a pressure-resistant stainless-steel towfish, high-strength Kevlar-armored cable, a waterproof deck unit, and proprietary OTech sonar software. The robust towfish design allows simple single-operator deployment and operation, supporting towing, hull-mounted, and side-mount configurations. An underwater overload protection shear pin provides impact protection, enhancing towfish safety. Its hydrodynamic design ensures stable towing performance. The ultra-low power consumption system supports both AC mains power and battery/inverter power supply.
The proprietary OTech software offers real-time image mosaicking, sonar image display, survey line planning and navigation, track tracking and coverage display, data logging and playback, target management/export, and multi-window sensor information display. Adaptive image equalization technology ensures consistent target presentation across near and far ranges. The software requires minimal parameter configuration, features simple operation, and has an intuitive UI. It exports industry-standard XTF format data for third-party post-processing software and supports customization to specific requirements.
