Low-Frequency Active (LFA) Sonar

Low-Frequency Active (LFA) sonar is a method used by navies and underwater researchers to detect and locate objects like submarines or underwater features. It works by emitting powerful sound waves at low frequencies into the water. These sound waves travel long distances, bouncing off objects they encounter. The sonar system then listens for the echoes to identify and pinpoint the location of those objects. LFA sonar is effective for deep and long-range detection but can impact marine life due to the intense sound levels involved.
