Definitions

  • the invention relates to a method for locating and clearing sea mines according to the preamble of claim 1. It uses a search and measurement sonar device, which is pulled by an unmanned towing vehicle at an adjustable towing depth, for the detection and localization of the mines, an unmanned, remote-controlled from a floating guide platform Clearing vehicle; and a data connection between the towing vehicle and the guide platform for transmitting the position data of the mines determined by the sonar device to the guide platform.
  • a search and measurement sonar device which is pulled by an unmanned towing vehicle at an adjustable towing depth, for the detection and localization of the mines, an unmanned, remote-controlled from a floating guide platform Clearing vehicle; and a data connection between the towing vehicle and the guide platform for transmitting the position data of the mines determined by the sonar device to the guide platform.
  • an unmanned, remotely controlled towing vehicle of the seahorse type pulls a search and measurement sonar device VDS through a route to be cleared of mines, whereby the search sonar detects and locates the mines to be removed.
  • the position data of the mine are passed on to the towing vehicle via cable, which forwards this data over a radio link to a guide platform remotely steering the towing vehicle.
  • this guide platform brings a Seewolf control drone to the mine in order to render it harmless.
  • search sonar can only determine the relative position of the mine in relation to its own position, an exact and continuous determination of the position of the search sonar on the one hand with respect to the towing vehicle and on the other hand with regard to the geographic position of the towing vehicle itself is necessary, so that ultimately the position of the mine in geographic coordinates determined and made available to the command platform for the combat drone.
  • the magazine also shows Soldier and technology in issue 3/1994 on page 150 a further development of the system Mine defense 2000 , in which a position beacon is placed near a located mine on the water's bottom, the sound signals of the mine-fighting drone of the type Seewolf signal the location of a mine.
  • the invention is based on this prior art.
  • DE 36 09 307 C1 describes a method for locating and destroying Known aquatic mines, in which an unmanned platform carrying a launcher on the Mine is pulled past and behind it a localization device at a predetermined distance follows. Behind the localization device there is in turn a predetermined distance Relocalization device and a destruction device following this. Between the First contact with the mine by the localization facility and subsequent relocalization At least two transponders are brought to the mine near the mine. At the The location of the mine relative to the transponders is then relocated, and the Measured data determined are either used to activate a destruction device used mine hunting torpedoes that drop an explosive charge near the mine, or they are fed to a fire control system, which is a facility that fires at the mine controls.
  • a major advantage of the invention is that complex tug body tracking from the towing vehicle can be omitted. Nevertheless, the location and control of the mines remain completely independent feasible from each other.
  • the process is divided into three phases, namely that Laying the transponder, locating the mines and locating them in with regard to the transponders and the introduction of the combat drone to the Transponder and the mine, the drone in one by the transponder certain coordinate system moves.
  • the transponders can either be operated from a helicopter or with the help of a Laying vehicle are exposed, for example of the same type or is the same as it later used for search and towing Survey sonar device is used.
  • This sonar is at a given depth hauled, but its geographic position does not need to be accurately determined and to be determined continuously.
  • the VDS Vehicle Depth Sonar
  • the VDS includes a sonar sensor for ground mines and Anchor mines as well as a sediment sonar for the detection of flooded sea mines. It measures the mine position in relation to at least three neighboring transponders. A compass in the sonar indicates its direction.
  • a depth sensor determines the Distance of the sonar above the water floor.
  • a measures Tug provided the relative distance between the Towing vehicle and at least three selected transponders.
  • An inertial system on the towing vehicle determines between the transponder measurements traveled path vectors.
  • the Velocity of sound measured in the individual water layers In this way you get the position of the individual transponders in a transponder-related Coordinate system. If you link this information with, for example, a GPS system determined geographic position of the towing vehicle, so you get the geographic position of the transponder. From this information and The determined position of the mine in the transponder coordinate system can be determine the geographic position of the mine, which is used for the initial control of the mine combat drone is needed. For an exact start of the mine, however the combat drone does not need to know its geographic position.
  • the drone is oriented in the transponder coordinate system and is based on the transponder-related mine data determined by the towing sonar headed.
  • the drone contains a transducer that opposes its relative position measures the transponders adjacent to the mine and in this way the drone Mine leads and destroyed.
  • the geographic position of the The towing vehicle can also be transmitted to the guidance platform and displayed there will. It is advantageous that the combat drone has neither its own inertial system needed, their respective position must still be determined. It is oriented rather in the transponder coordinate system. This will make for her Target control required device-related effort in the drone itself Minimum reduced so that these are trained for single use and nevertheless the proceedings can be carried out at reasonable costs.
