The DSF-3 is a dipping sonar system, which is mainly "passive sonar" that detects and tracks submarines and surface vessels. It can estimate movement's data of the vessels by receiving and processing underwater sounds produced by such vessels. This system can also be modified to be "active/passive sonar", with regarded to customer requirements. This system has been designed to operate on surface vessels and its antenna is thrown in to the water and dives to appropriate depth by a simple winch. In addition, the system can be minimized as a tactical system, which is able to operate on small ships or boats. At this situation the antenna is thrown in water by hands.
