Low-Frequency Active Towed Sonar
LOW-FREQUENCY ACTIVE TOWED SONAR Full-feature, long-range, low-frequency active and passive variable depth sonar (VDS) The Low-Frequency Active Sonar (LFATS) system is used on ships to detect, track and engage all types of submarines. L3Harris specifically designed the system to perform at a lower operating frequency against modern diesel-electric submarine threats. FEATURES > Compact size - LFATS is a small, > Full 360° coverage - a dual parallel array lightweight, air-transportable, ruggedized configuration and advanced signal system processing achieve instantaneous, > Specifically designed for easy unambiguous left/right target installation on small vessels. discrimination. > Configurable - LFATS can operate in a > Space-saving transmitter tow-body stand-alone configuration or be easily configuration - innovative technology integrated into the ship’s combat system. achieves omnidirectional, large aperture acoustic performance in a compact, > Tactical bistatic and multistatic capability sleek tow-body assembly. - a robust infrastructure permits interoperability with the HELRAS > Reverberation suppression - the unique helicopter dipping sonar and all key transmitter design enables forward, aft, sonobuoys. port and starboard directional LFATS has been successfully deployed on transmission. This capability diverts ships as small as 100 tons. > Highly maneuverable - own-ship noise energy concentration away from reduction processing algorithms, coupled shorelines and landmasses, minimizing with compact twin-line receivers, enable reverb and optimizing target detection. short-scope towing for efficient maneuvering, fast deployment and > Sonar performance prediction - a unencumbered operation in shallow key ingredient to mission planning, water. LFATS computes and displays system detection capability based on modeled > Compact Winch and Handling System or measured environmental data. - an ultrastable structure assures safe, reliable operation in heavy seas and permits manual or console-controlled deployment, retrieval and depth- keeping.
