Definitions
- LFK guided missiles
- IR radiation emitted by the vehicle or RF radiation reflected from the vehicle to switch to that radiation and thus to the vehicle to hit it.
- fake targets are issued as a protective or countermeasure, which then interrupt the line of sight in the IR or RF range between threat and vehicle or move away from the driving tool to create a more interesting target for the threat, so this on the new decoy goes on.
- the vehicle can then be led out of the danger zone.
- Such fake targets are controlled by a weapon system, such as a launcher, wherein effective masses produce the protective measure.
- EP 0 805 333 B1 discloses a method for providing a decoy target, which is characterized in that, via an activation and distribution device, which is arranged centrally, the IR and RF active materials are activated and swirled or distributed.
- the target search head acting in one of the two or at the same time in both wavelength ranges receives a radiation emitted in the IR range and a retroreflective RF radiation onto which the homing seeker switches.
- EP 2 612 101 B1 discloses an apparatus and a method for producing an effective fog wall.
- DE 103 46 001 B4 takes into account the type of missile, the missile attack direction, the missile removal and the Flugkör per-speed.
- the kinematic data of the ship will be like Vessel speed, the ship's own movements, the direction of travel of the ship, the ship's aspect / signature, as well as the environmental data such as wind speed and wind direction. From these an optimal solution for protection is determined.
- the missile defense or contactor is largely dependent on the relative wind in most cases. In a defensive or defensive situation, situations can frequently arise in which the calculated solution (defense or protective measure) is unsatisfactory due to the environmental parameters.
- the present invention therefore has the object to remedy this disadvantage.
- the invention is based on the consideration that a change in the relative wind takes place on the protective measure already due to the new position assumption of the vehicle, especially in a course change of the vehicle.
- a wind from north-north-east can hit the vehicle from the front before the course changes, and now, after the change, it can be seen from the side. If this change is not taken into account by the system when applying the countermeasure, the situation may arise in which optimum application of the countermeasure is no longer possible or can no longer be ensured.
- the system e.g. one or more launchers in conjunction with at least one computer, for example a so-called fire control computer, and servo motors for aligning the launcher or the like, can no longer deploy the countermeasure in good time or only with ineffectiveness.
- a course change also takes a certain amount of time.
- the threat approaches the vehicle at high speed.
- the search parameters of the threat e.g. Depth of the radar door (depth range) and the (absolute) width of the radar lobe in an RF-LKF.
- a depth range which the seeker head observes is defined by the pulse repetition frequency and the pulse repetition interval of a radar signal originating from an LFK (threat). Anything outside this range is not included in the calculation by the LFK.
- the aim is therefore to shoot precisely in this area, to implement the countermeasures and to achieve a separation from the vehicle on the other hand, to bring the vehicle out of this range as far as possible at the end, that is, that the vehicle is out of this range as far as possible.
- the resulting situation is now calculated for each course and ride combination.
- the vehicle takes that combination, there actually is a shot solution.
- This will be displayed accordingly. Since it is according to the invention to changing vectors and directions and the representation of a set (in the mathematical sense) of the course and driving recommendations.
- course and driving changes result from a new constellation of wind direction and strength, threat direction and distance.
- a goal-oriented course change and a concomitant change in the relative wind are taken into account.
- a clear improvement of the calculated solution is obtained or made possible in the first place.
- the available kinematic data of the vehicle is used to determine the time needed to change the course (direction of travel) and the journey (speed).
- this data which is available for each course / journey combination, and other current data, such as relative wind, new threat distance, new relative direction of threat
- a solution corresponding to these new circumstances is calculated or calculated.
- the threat direction the threat type (spot number), the wind (direction, strength), the own course, the journey, like e.g. Geschwin speed, the loading state of the system, as well as dead zones of the system or the launcher, etc. used.
- additional vehicle or ship data such as size, tonnage, drive type, etc., can be taken into account.
- the position (cloud position) for the adjacent threat situation is determined and made available.
- the specifiable Data such as various wind directions, wind speeds, first contacts to the threat etc. are stored, the solutions are calculated. From this data, in comparison with the determined data, course and travel combinations are calculated, then the quality of the solution is calculated and displayed. It mainly takes into account only the course and journey combinations achieved by the system until a threat, such as missiles, has hit the system to prevent unnecessary delays in the solution volume.
- a solution quality an important role.
- the solution quality can be calculated on the basis of defined algorithms.
- quality of solution is meant the quality, which provides information about the achievable separation of decoy and vehicle. This quality is determined depending on the location of the decoy and the radial and lateral components of the rela tive wind from the threat point of view. Therefore, the quality of the solution is calculated and displayed for all still achievable course and drive combinations.
- the representation can be made on a display of the system. The operator can therefore react in an optimized manner to the specific threat situations and select and express corresponding course and driving recommendations.
- Fig. 3 is a visualized representation in the form of a polar representation.
- a specific decoy pattern 1 1 is generated.
- a suitable decoy pattern for each missile is stored in the database 10 of the fire control computer 7. This pattern can then be retrieved by the fire control computer 7 in order to build up a corresponding decoy pattern 1 1.
- the calculation of the ballistic trajectories of Täuschkör permunitionen (decoys) 12, etc. reference is made, for example, to DE 103 45 001 B4.
- Fig. 2 shows a simple overview of the procedure of the method. In a first step of this expansion, each attainable course and journey combination is determined.
- the fire control computer 7 begins to calculate the solutions or solution quantity and to determine the quality of the solution on the basis of the available data and information for all still achievable course and drive combinations. These solutions can then be visualized to an operator on a display 13 (FIG. 3). The calculation of the quality of the solution for each course and ride combination is thus at least based on a given wind situation and egg ner predetermined threat. 3
