Warning and signalling device, especially for maritime purposes

摘要

The present warning and/or signalling device is intended to provide radar signal reflections for locating a ship or an aircraft wreck or reflected warning signals when sensing the approach of a vessel, such as a submarine. For this purpose a radar reflector forms a unit with a first buoyancy or lift structure. The unit in turn is stored in a second buoyancy or lift structure which may be placed below or above sea level. The second buoyancy or lift structure is further equipped with identification and/or other types of sensors.
