Variants of LFA (low-frequency active) dipping sonar are developed to improve the operational capability and effectiveness of ASW (antisubmarine Warfare) helicopters. LFA dipping sonar incorporated with precisely defined pings and variable depth dip capability performs well when used multistatically with the latest passive buoys. LFA source buoys give helicopters the option for using its dipper in receive-only mode. Their long life could be exploited to deter, divert, or distract a submariner, and could be used with passive buoys to relocate and track long-range targets, while helicopter is maneuvering. System performance is affected by many factors such as dipper or sonobuoy operating depth and sensor geometry. A single helicopter using LFA dipper and sonobuoys could provide effective search against the threat of deploying modern diesel submarine. Sonobuoy provides ASW helicopters benefits such as greater tactical flexibility, efficient tracking, and a true maritime patrol capability all in a single avionics box.
