Underwater Side-Scan Sonar Provides Scanned and 3D Views of Riverbeds and Waterways

Underwater Side-Scan Sonar utilizes the underwater propagation characteristics of sound waves to perform underwater detection through electro-acoustic conversion and information processing. Equipped with a 7-inch high-brightness IPS screen, it supports independent control of four- or six-way split-screen displays. Rated for a pressure depth of ≥300 meters and featuring an IP68 waterproof rating, it is designed for use in underwater salvage and rescue operations.

Underwater Side-Scan Sonar is an electronic device that performs detection tasks by leveraging the underwater propagation properties of sound waves. Its operating principle is based on electro-acoustic conversion and information processing; by emitting sound waves and receiving the returning echoes, it generates images of underwater structures. This device provides scanned and 3D views of riverbeds and waterways for underwater salvage and rescue operations, and is also capable of detecting underwater biological activity. It assists operators in gaining an intuitive understanding of underwater topography and target distribution, thereby enhancing the efficiency of underwater operations.

The device features a 7-inch IPS screen with a resolution of 1200×900 and a brightness of 1200 nits, ensuring clear image display even in bright-light environments. The screen utilizes a Chinese-language operating system and supports four-way or six-way split-screen display modes, allowing users to view four or six separate feeds simultaneously. Each feed can be controlled independently, and the interface layout can be customized to suit specific operational requirements. Key parameters—such as positioning information, water temperature, time, and current depth range—are displayed on the screen, providing a comprehensive data reference for field operations.

In terms of control design, the device features five customizable shortcut buttons. Users can configure these buttons to access frequently used functions, thereby reducing the time spent navigating menus and improving operational efficiency in the field. The screen offers a wide viewing angle of 160 degrees both vertically and horizontally, accommodating the usage requirements of various mounting positions and viewing angles.

The device is rated for a pressure depth of no less than 300 meters and meets the IP68 waterproof standard, making it suitable for prolonged underwater operations in both freshwater and saltwater environments. Regarding detection range capabilities, the maximum depth for downward-scanning structural analysis is no less than 90 meters; the maximum depth for side-scanning structural analysis is no less than 180 meters; and the overall maximum detection depth is no less than 300 meters. This detection capability effectively covers the salvage and rescue requirements for most inland waterways and near-shore coastal areas. In practical applications, the Underwater Side-Scan Sonar utilizes acoustic imaging technology to generate high-definition images of underwater structures. It can be employed to search for persons fallen into the water, locate sunken vessels, detect underwater obstacles, and assess riverbed topography. Based on real-time transmitted imagery, rescue personnel can determine the precise location and orientation of targets, formulate salvage strategies, and minimize the time spent on blind searches. The device features a compact overall design, offering excellent portability and ease of deployment, making it well-suited for applications in emergency response, firefighting and rescue operations, and underwater engineering surveys.
