Forward Looking Sonar

Forward Looking Sonar / Forward Facing Sonar

A Forward-Looking Sonar (FLS), or forward-facing sonar, is an advanced imaging system used to create real-time, high-resolution 3D images of underwater objects and obstacles ahead of a vessel or underwater vehicle. By emitting sound waves and analyzing their reflections off objects in the water, 3D forward-looking sonars provide crucial information about the surrounding underwater environment, including seafloor topography, submerged structures, and marine life.
