Definitions

  • the invention relates to a missile mission unit for a missile, to which Sensors for the movement of a target relative to the missile and for the Self-motion of the missile are connected, containing means for detection and Identification and determination of the track of the target, that of data of the sensors resources for situational assessment and analysis from the information about location, type and track of the destination, a first database in which knowledge about potential targets are stored, a second database in which data about the Skills of the missiles are stored, and means of generating plans for Actions and from this are activated to generate decision criteria,
  • target-tracking Missiles On a combat aircraft are in use usually several target-tracking Missiles suspended in launchers under the wings.
  • the target-tracking Missiles have seekers with sensors that target one or more targets to capture.
  • the missile inertial sensors may contain, which on the Respond to movements of the missile in the inertial space. From viewfinder signals of Seekers are generated steering signals that lead the missile to the target.
  • From viewfinder signals of Seekers are generated steering signals that lead the missile to the target.
  • sensors which on the movement of the Aircraft, such as inertial sensors or satellites navigation receivers, and sensors that detect targets in the field of view, such as radar and / or Infrared devices.
  • sensors In a manned combat aircraft, the pilot must select a destination select a missile to attack the target and the missile to the target instruct, i. make sure the seeker has captured the target.
  • the type and He will be the one or the other select another missile and shoot.
  • a fast and agile target In With a short distance he will be a fast and agile missile may select a lower range. Another missile is possibly more suitable for slower targets at greater distances.
  • the vote between a missile with active radar seeker and a missile with a passive infrared seeker may u. depend on the distance of the target, the Environmental conditions and the available to the opponent Countermeasures. Also critical is the time of the launch of the selected Missile.
  • the pilot receives a variety of visual or audio signals from the various sensors, which he has to process and from which he has to make his decision. additionally of course, the pilot must fly the fighter jet in aerial combat. The pilot must also watch out for threats such as from enemy missiles and if necessary, avoid such threats and activate countermeasures. This can overwhelm the pilot and lead to fatal mistakes.
  • This missile mission unit contains stored knowledge in the form of data and / or facts necessary for the mission of Missile are relevant. This can be data showing the characteristics of the Characterize missiles themselves, such as speed, maneuverability (maximum lateral acceleration), range, etc. This can also be data over Characteristics of potential goals.
  • the missile mission unit receives data from Sensors. These are the data from your own sensors Missile. But this can also be data from sensors of the platform, e.g. the radar, or from the sensors of other missiles mounted on the platform.
  • the Missile Mission Unit then provides the pilot with decision criteria for the mission Use of the associated missile. It can then be e.g. be displayed that Missile "1" is more suitable for the present situation and a specific objective as missile "2". In a manned fighter but then the pilot is the make final decision. He is, however, relieved of a lot of information. This information is preprocessed by the missile mission unit.

Preferably but is the or each missile mission unit in the associated missile arranged and connected to the platform via a standardized interface. Then is when inserting a certain type of missile into the launcher over the Automatically interface the missile mission unit designed for this type of missile switched on in the computer network. It is not an intervention in the platform-side mission avionics required.
  • the invention relates to an advantageous embodiment of a missile mission unit of the type mentioned, as described by DE 197 16 025 A1 and, in particular, the training of the means for the production of plans for actions.

  • the results of the situation prediction are on means for Calculation of missile ranges, possibly with respect to the target or, if applicable, different destinations may be available for different available types of missile.
  • the missile mission unit From the prediction of the future change of the situation, the missile mission unit recognize and if necessary make visible to the pilot, whether the goal of one launched missile at the flight condition of the platform (of own aircraft) can be detected or not. Does the platform carry several missiles? Types, it can be determined by the missile mission unit, which of these Missile with the best prospects of success should be shot down.
  • the results of the calculation are optimal Inferential for the production of reaction proposals switched.
  • These inference means are preferably of a learning capable, suitably trained neuro-fuzzy Structure formed. They contain “rules” approximately in the form: “If the goal without Another maneuver of the aircraft in the firing range of the missile is, then fire the Missile off "," If the target is slightly out of the firing range of the Is missile, then perform this or that maneuver to the target in the Shot area of the missile to bring "etc.

  • the viewfinder 14 contains a plurality of different ones Sensors. The viewfinder may u.U. "see" several objects at the same time.
  • Objects and potential targets supplied data are processed by image processing Detection of objects, ie a determination of where an object is located. Furthermore, it takes place an identification of the objects with regard to friend / enemy recognition.
  • image structures e.g. known types of aircraft with the image-resolving sensors supplied image structures.

  • Block 28 is a database in which knowledge about potential goals is stored are. It is known what flight characteristics a type X aircraft has and which air combat tactics in a given situation usually with a Type X aircraft are applied. If the target as a type X aircraft and the situation is recognized, then one can estimate from it, how the goal in the next future is expected to behave.
  • Block 34 symbolizes the evaluation of the results of block 34 shown calculations. The result of this evaluation is on inference means 38 "Switched".
  • These inference means 38 are of a learning capable, suitably trained neuro-fuzzy Structure formed. They contain “rules” approximately in the form: “If the goal without further Maneuver of the aircraft in the firing range of the missile, then fire the missile from ",” If the target is slightly out of the firing range of the missile, then Perform this or that maneuver to bring the target into the firing range of the To bring missiles "etc. The inputs" within “or” slightly outside “ are thereby linquistic inputs, which are registered by "Fuzzy Logic”.
