​What is a Multibeam Sonar?

Multibeam sonars are advanced acoustic technology that uses multiple sound waves (or "pings") to create detailed, high-resolution images of the seafloor and submerged objects. Unlike traditional single-beam sonar​, which sends a single sound pulse straight down to the seabed, multibeam sonar sends out multiple beams in a fan-shaped pattern. These beams allow for a much wider swath of the seabed to be mapped simultaneously, resulting in faster, more comprehensive surveys. 

The sonar system measures the time it takes for each sound wave to bounce back after hitting the seabed or underwater objects. By analyzing these return times, the system generates precise, three-dimensional maps of the underwater environment. This makes multibeam sonar ideal for creating detailed bathymetric maps, detecting underwater hazards, and assessing environmental conditions. ​

Key Applications of Multibeam Sonar

Teledyne Marine's multibeam sonar systems are versatile and can be used in a variety of applications, including: 

• Hydrographic surveys: Mapping the seafloor for nautical charting and navigation. 

• Seabed characterization: Assessing sediment types, underwater features, and topography. 

• Environmental monitoring: Studying marine habitats and monitoring changes in ecosystems. 

• Underwater inspections: Inspecting infrastructure such as pipelines, bridges, harbours, and submerged structures. 

• Offshore exploration: Supporting resource extraction in deep-water environments. 

Teledyne Marine Multibeam Sonar Systems

At Teledyne Marine, we provide a range of multibeam sonar solutions tailored to meet the needs of various applications and environments, from shallow coastal waters​ to extreme deep-water depths. 

Shallow Water Multibeam Sonar

In shallow water, multibeam sonar systems play a critical role in fast and efficient surveying of the seafloor, especially where accuracy and high-resolution data are essential for navigation and infrastructure projects. Teledyne Marine's shallow water multibeam sonar systems are designed to operate effectively in environments where water depth may range from just a few meters to several hundred meters. 

Our shallow-water systems​ are equipped with advanced features that allow for precise mapping of intricate coastal features, nearshore bathymetry, and navigation channels. Whether it's charting port entrances, conducting habitat assessments, or monitoring environmental changes, our multibeam sonar systems deliver high-resolution, reliable data. The systems are also optimized for integration with remotely operated vehicles (ROVs), autonomous underwater vehicles​ (AUVs), and unmanned surface vehicles​ (USVs), ensuring seamless operations across a variety of platforms. 

Deep Water Multibeam Sonar

Teledyne Marine's deep water multibeam sonar systems are designed to perform in some of the most challenging environments on Earth. These systems are engineered to withstand extreme depths, high pressures, and low temperatures, making them ideal for applications in subsea exploration, oil and gas surveys, and scientific research. 

Operating in deep water often means navigating through vast and complex underwater environments, where achieving accurate mapping and reliable data collection is critical. Teledyne Marine's deep-water multibeam sonars provide highly detailed 3D maps, enabling users to detect and analyze underwater structures, geological formations, and environmental conditions at depths that extend several thousand meters below the surface. 

Our deep-water systems​ are equipped with high-frequency beams that provide exceptional resolution and clarity, even at great depths. These sonars are essential tools for oil and gas operations, subsea construction, marine geology, and environmental monitoring, where precise mapping and real-time data are crucial for safety, efficiency, and decision-making. 

Benefits of Multibeam Sonar

High Resolution and Accuracy

One of the key advantages of multibeam sonar over traditional single-beam sonar​ is its ability to capture much more detailed data. With multiple beams emitting sound pulses in a wide swath, multibeam sonar systems can map large areas of the seabed in a fraction of the time. This high-resolution data allows for the creation of precise 3D models and bathymetric maps that can be used for navigation, hazard detection, and environmental assessments. 

Faster Surveys

The wide swath coverage provided by multibeam sonar systems means that large areas can be surveyed quickly and efficiently. This is particularly important in commercial and scientific applications where time and cost are critical factors. Whether you're surveying an entire coastal region or mapping an offshore pipeline route, Teledyne Marine's multibeam sonar systems help you get the job done faster without compromising on data quality. 

Enhanced Data for Complex Environments

Multibeam sonar is essential for mapping complex underwater environments, such as irregular seabeds, submerged structures, and challenging topographies. With higher accuracy, multibeam sonar systems can detect small variations in depth and provide a clearer understanding of the underwater landscape. This is especially valuable in both shallow and deep-water settings, where underwater features may be difficult to detect with traditional sonar systems.
