Operation at three different frequencies provides optimum flexibility: Low Frequency (100kHz) mode provides visualization and detection of objects in the water column and on sea floor to ranges up to 800m or more. Medium Frequency (200kHz) mode is typically used for high accuracy localization in surveyed areas, and primary detection in shallow waters and reverberant environments. High Frequency (400kHz) mode provides high resolution shadow classification data during offshore underwater inspection and MCM usage.

SeaBat F30

The SeaBat F30 is a High-Resolution Forward-Looking Sonar System designed specifically for 12 ¾ inch (approx. 324mm) AUVs/UUVs. The SeaBat F30 operates at 200 kHz or 635 kHz illuminating a wide, 120° horizontal sector ahead of the Sonar Head Assembly.

Forward Facing Sonar Solutions

Teledyne Marine offers advanced forward-facing sonar systems designed for real-time imaging and obstacle detection in challenging underwater environments. Our forward-looking sonar and forward imaging sonar solutions are engineered to provide precise, real-time data to enhance navigation, ensure safety, and support underwater inspections. These systems are ideal for use in a variety of marine applications, from autonomous underwater vehicles (AUVs) to remotely operated vehicles (ROVs) and surface vessels.

What is a Forward Facing Sonar?

A forward-facing sonar, also known as forward-looking sonar or forward imaging sonar, is a sonar system that is designed to provide high-resolution imaging of the underwater environment in front of a vessel or vehicle. Unlike traditional sonar systems, which typically measure the depth below the vessel or capture data in a single direction, forward-facing sonar systems allow users to scan the area in front of them, detecting obstacles, submerged structures, and other features that might pose a risk or provide important data for a mission.

Forward-facing sonar systems are widely used in navigation, particularly in environments where visibility is poor, such as in turbid waters or at night. They are also commonly used for underwater inspections, search-and-rescue missions, and operations in confined or complex environments like ports, harbors, and pipelines.

How Does Forward Looking Sonar Work?

Forward-looking sonars operate on the same basic principles as traditional sonar systems: it sends out sound waves (or acoustic pulses) into the water. These pulses travel until they hit an object or the seafloor, where they are reflected back to the sonar system. By measuring the time it takes for the sound waves to return, the system calculates the distance to the object or surface and generates a visual representation of the underwater environment.

However, unlike single-beam or multibeam sonar, forward-facing sonar systems are oriented to scan the area in front of the vessel or vehicle. This allows for real-time imaging of submerged obstacles and terrain, making it an invaluable tool for navigation, underwater inspections, and research.

Forward-facing sonar can be equipped with various imaging modes, such as 2D or 3D imaging, depending on the specific application. These systems provide a detailed view of the surroundings, helping operators make informed decisions during critical missions.

Key Applications of Forward Imaging Sonar

Navigation and Collision Avoidance

One of the primary applications of forward-facing sonar is navigation, particularly in environments where traditional optical or GPS-based navigation methods are not effective. In low-visibility conditions, such as turbid waters or dark environments, forward-looking sonar provides operators with a clear view of obstacles in the path of a vessel, ROV, or AUV. This helps avoid collisions and ensures safe navigation in confined spaces.

Underwater Inspections

Forward imaging sonar is commonly used in underwater inspection tasks, such as inspecting pipelines, bridges, dams, and other submerged infrastructure. By providing a clear, real-time view of the area in front of the vehicle, forward-facing sonar allows operators to detect damage, corrosion, and other issues that might not be visible using other inspection methods.

Search and Rescue Operations

During search-and-rescue operations, forward-facing sonar is invaluable for locating objects or individuals in the water. The sonar can scan large areas quickly, providing high-resolution imagery of submerged hazards, wreckage, or people in distress. This capability is crucial in emergency situations where time is of the essence.

Scientific Research and Exploration

Forward-facing sonar is also used in scientific research and underwater exploration, particularly for mapping the seafloor, studying marine ecosystems, or searching for archaeological sites. The real-time imaging capabilities of forward-looking sonar enable researchers to gather important data without disturbing the environment or relying on traditional visual methods.

Benefits of Forward Facing Sonar

Real-Time Imaging

One of the key advantages of forward-facing sonar systems is their ability to provide real-time imaging of underwater environments. This allows operators to see the conditions in front of their vehicle or vessel as they navigate, helping them make quick decisions and avoid obstacles in real time.

Enhanced Safety

Forward-facing sonar enhances the safety of underwater operations by providing early detection of submerged objects, obstructions, and other hazards. This can prevent collisions, damage to equipment, and costly delays in operations, ensuring the safety of both the crew and the equipment.

Versatility and Adaptability

Teledyne Marine's forward-looking sonar systems are versatile and can be used across a range of platforms, including surface vessels, ROVs, AUVs, and USVs (unmanned surface vehicles). They are designed to operate in a variety of underwater environments, from shallow coastal regions to deep-water exploration sites, making them ideal for diverse marine applications.

High-Resolution Data

Teledyne Marine’s forward imaging sonar systems provide high-resolution data that enables operators to identify and assess obstacles, structures, and environmental features in front of them with exceptional clarity. Whether it's detecting submerged debris, mapping the seafloor, or inspecting infrastructure, the high-quality data captured by forward-facing sonar is invaluable for accurate decision-making.
