  • the method includes an overlap operation and a handoff operation.
  • the object of the invention is to provide improvements in DIRCMs.
  • the object is achieved by a method according to patent claim 1 for combating an approaching target by means of a DIRCM system, a DIRCM system according to patent claim 12 for carrying out the method and an object according to patent claim 15 with said DIRCM system.
  • the DIRCM system contains an interface to a warning system.
  • the warning system is used to report approaching targets to the DIRCM system via the interface.
  • the DIRCM system contains at least two DIRCM modules or subsystems. Each of the modules is used to track the target in a tracking mode (so-called “tracking") and to attack the target in a beam mode (so-called “jamming").
  • Tracking means locating the target, in particular the above-mentioned IR seeker head, so that targeted irradiation is possible.
  • combating is carried out by irradiation, i.e. emitting radiation, in particular the above-mentioned laser beam, which is beamed into the seeker head in a targeted manner, i.e.
  • the module contains in particular a tracking unit that carries out the tracking and a beam unit that carries out the irradiation.
  • the beam unit contains in particular a jamming laser for irradiating the target.
  • Each module or its tracking/beam units are housed in so-called “turrets" or are structurally concentrated or integrated.
  • Each of the modules has a total area for tracking and/or fighting targets. In particular, tracking and fighting is possible in the total area. However, it is also conceivable that - especially at the edge of the total area - only tracking or fighting is possible. However, these edge areas are so small that they can be neglected.
  • the total area is therefore the entire spatial area in which - especially in the case of a module installed on a platform to be protected - the module has potential targets. can track and/or fight or irradiate.
  • the overall area usually contains a solo area in which the relevant module alone is available for tracking and/or fighting the target. Alternatively or additionally and also usually, the overall area contains an intersection area with at least one, in particular exactly one, of the other modules.
  • the procedure consists of the following steps:
  • a step A) is carried out when the target is reported by the warning system.
  • the modules In this case, exactly one of the modules is selected as the active module for this target.
  • the tracking mode and the beam mode are activated for the target. All other modules remain deactivated for this target.
  • the module in question therefore begins tracking and irradiating or attacking the target and continues to do so until further notice.
  • the statements below always apply to a specific target. The system can attack other targets in parallel. However, this will not be taken into account here.
  • step A a specific module is activated based on the detection of a target by the warning system. This applies in particular to the case where a target is newly reported in the defense area. This means that a target is detected in the defense area for the first time or is detected again after being lost (e.g. if the pursuit is accidentally broken off).
  • step B) is carried out if the target is in one of the solo areas.
  • the tracking mode and the beam mode are switched or remain switched on for the active module associated with the solo area in question. activated.
  • the modes are already activated and therefore remain activated, so they do not need to be reactivated.
  • the active module continues to track and engage the target. Tracking mode and beam mode on all other modules are or remain deactivated (depending on the previous state).
  • a step C) is carried out if the target is in the intersection area between the active module and a second of the modules.
  • the (only) active module forms a first module.
  • a single active module is present in particular or regularly because the target was either detected in the intersection area and exactly one module was activated according to step A) or the target enters the intersection area from a solo area, in which case the only module responsible in the solo area according to step B) is the currently active module.
  • step C either a step C2) (see below) or a step C1) is carried out as follows: In a first step C1a), the tracking mode and the beam mode are deactivated on the first module. In a subsequent step C1b), after the first module has been deactivated, the tracking mode and the beam mode are activated on the second module. In particular, in step C1), by deactivating the first module and then activating the second module, the target or its tracking and combat is transferred from the first to the second module. The second module is now the active module.
  • Step C1 After the active module changes from the first to the second module according to step C1), the following applies: The second module now becomes the "active" and thus the "first” module in the next step C). As a result, i.e. when a step C1) is carried out again, a handover back to the previous (but now "second” module) or a handover to a third (previously uninvolved, now "second") module can also take place if other modules are responsible in the cutting area. Step C1 can therefore be carried out again if required or desired.
  • one of the modules is to be selected in step C1) or C1b) which is to then take over tracking and/or irradiating the target as the second module.
  • step C2) is carried out as follows:
  • the tracking mode and beam mode remain activated for the first (active) module.
  • the target continues to be tracked and irradiated or attacked by the first module. This applies in particular if a target moves from a solo area in which it has already been or is being tracked and irradiated by the first module into the adjacent cutting area.
  • the first or active module continues to track and irradiate without interruption.
  • Steps C1) and C2) can therefore also be carried out alternately or repeatedly as long as the target is in the intersection area or has not been successfully attacked, i.e. if either the active module is to remain active or a further handover to another module is to take place.
  • the target is in particular a missile or rocket.
  • the warning system is in particular a missile warning system (MWS).

  • a module when activated, its tracking unit, which carries out the tracking, and its beam unit, which carries out the irradiation, must be "free" or available in order to be able to track and irradiate the target in question.
  • any module that is not occupied by tracking and/or irradiation at a certain point in time is free at any time to track and/or irradiate another target.

  • the DIRCM system decides (handover criterion) on the change from one turret to the next (selection criterion). If a handover becomes necessary, the newly selected (second) turret swivels towards the incoming threat, e.g. based on the information from the warning system regarding the approach area, without activating its tracking mode.

This variant assumes that the above-mentioned approach range for the target is available and used by the warning system.

  • the module 12b is deactivated (tracking mode MV and beam mode MS deactivated).
  • the detection areas 17a,b of the modules 12a,b or of their tracking units 16 are also shown. As soon as the target 4 is initially located within such a detection area 17a,b of the modules 12a,b, the target can be detected exactly in the respective target area when the tracking mode MV is activated (cross marking).
  • the warning system 10 provides the (rough) approach area 11 of the target 4.
  • This approach area 11 is now used to swivel the second module 12b - with the MV tracking mode and MS beam mode still deactivated - towards the target so far that the target comes into the detection range 17b of the module 12b or of its tracking unit 16.
  • the swiveling is shown by the arrow 28.
  • the tracking unit 16 has not yet swiveled far enough towards the target 4. Its detection range 17b is still far away from the target 4. Activating the MV tracking mode on the module 12b could not yet lead to successful tracking by the module 12b.
