Definitions

  • the present invention relates, in general, to the field of Electronic Countermeasures (ECMs) and, in particular, to Directed Infrared Countermeasure (DIRCM) systems (sometimes also referred to as Directional Infrared Countermeasures).
  • ECMs Electronic Countermeasures
  • DIRCM Directed Infrared Countermeasure
  • DIRCM systems are used to defeat infrared (IR) guided missiles, such as those ones launched by man-portable air-defense systems (MANPADS).
  • MANPADS man-portable air-defense systems
  • a DIRCM system is an active IR countermeasure system designed to be effective against IR seekers of IR-guided missiles (typically, the so-called first three generations of IR seekers).
  • a DIRCM system is designated to a specific target by a Missile Warning System (MWS), which keeps sending an updated list of detected threats (said list reporting a coarse estimation of a direction of arrival of each detected threat).
  • MFS Missile Warning System
  • a DIRCM system tries to deceive the IR seeker of an approaching IR-guided missile so as to steer the latter away from its target by means of a narrow laser beam, that is constantly kept on the missile and is modulated according to a jamming code related to the seeker's generation(s) which the DIRCM system is designed to be effective against.
  • a DIRCM system typically comprises a tracking unit (or tracker), a laser unit and an electronic control unit, wherein:
  • the tracker is typically configured to:
  • the tracker and the laser unit are integrated into a steerable turret, which is operable by the tracker to achieve the requested pointing.
  • the DIRCM system according to US 2007/0075182 A1 comprises:
  • the pointer-tracker according to US 2007/0075182 A1 slews the gimbal to the threat coordinates to initiate tracking and then processes the data from its detector to refine tracking of and verify the threat, and, if verified, engages the IR laser to emit a modulated IR laser beam through the laser transmitter to jam the IR missile seeker.
  • Single turret DIRCM configurations could lead to have large blind zones around the installation platform where approaching threats are not countered at all.
  • the FOR of a single turret DIRCM system does not depend only on the DIRCM system itself, but also on the installation platform, which always masks several portions of the theoretically-achievable coverage area, even when considering the most extended possible FOR for the single turret DIRCM system.
  • single turret DIRCM configurations are limited to protecting a platform against one threat at a time.
  • multiple independent turret DIRCM configurations can be used.
  • this configuration type is exploited to reduce blind zones around large platforms.
  • multiple turret DIRCM systems typically lack coordination among the several turrets and this lack of coordination does not allow to counter more than one threat per sector at a time.
  • the need to assign a specific sector to each turret mainly derives from the lack of a protection mechanism guaranteeing non-destructive interference between different laser beams.
  • Figure 1 shows an example of field of regard coverage achievable with a twin turret DIRCM configuration installed on an aircraft (denoted as a whole by 1).
  • Figure 1 is a bottom view of the aircraft 1, which is equipped with two DIRCM turrets 11 and 12, each designed to counter threats in a respective azimuth sector 111/112, wherein said azimuth sectors 111 and 112 fully cover the 360° azimuth spanning and overlap in two common regions 113 and 114.
  • the reason for not allowing any assignment of one and the same threat to both the turrets 11 and 12 is to avoid destructive interference between the lasers of the two turrets 11 and 12, which destructive interference would cancel the jamming effect on the target's seeker.
  • EP 2 442 131 A1 which forms a starting point for the independent claims, concerns a laser DIRCM (or LDIRCM) system mountable on a platform including a plurality of sector units.
  • Each sector unit may include at least one laser unit and a laser guidance module.
  • the laser unit may be adapted to generate a laser beam or laser energy that is intended for jamming a guidance system of a threat.
  • the laser unit may be coupled to the laser guidance module.
  • the laser guidance module may be adapted to steer at least a laser beam generated by the laser unit towards a threat.
  • each one of the plurality of sector units is configurable to provide, when mounted on the platform, a jamming capability in respect of a threat located within a sector that is substantially less than 180° horizontally.
  • the plurality of sector units are mountable on the platform such that each one of the sector units is configurable to provide a jamming capability in respect of a threat located within a different sector relative to the platform.
  • the threat jamming capability of the LDIRCM system according to EP 2 442 131 A1 is defined by the aggregate of the different sectors covered by each one of the plurality of sector units.
  • JP 2006 207891 A relates to a light-wave interfering device capable of simultaneously dealing with a plurality of flying objects to further improve safety and defending performance.
  • Said light-wave interfering device comprises a plurality of interfering portions, and the information on flying objects acquired by a flying object alert portion is given to any of interfering portions through a control portion.
  • the control portion recognizes coverage of each of interfering portions, and the information on flying object is given to the interfering portion expanding the coverage, when the flying object arrives at any coverage.
  • the interfering portion extracts the azimuth direction of the flying object when the information on flying object is given, and irradiates the azimuth direction with interference light to interfere with a course of the flying object. Further an evaluation function is introduced to evaluate "which flying object is dealt by which interfering portion" while applying the evaluation function as an index. As the flying object can be dealt by the optimum interfering portion at all times, the defending performance can be improved.
  • An object of the present invention is, thence, that of overcoming, at least in part, the above drawbacks of the current multiple turret DIRCM systems.
  • the present invention concerns a method of operation of a DIRCM system for protecting a platform against IR-guided missiles in accordance with independent claim 1, wherein said DIRCM system comprises a plurality of DIRCM subsystems operable to track and jam IR-guided missiles, and wherein the DIRCM subsystems comprise a first DIRCM subsystem and a second DIRCM subsystem, that are installed on the platform so that:
  • the DIRCM system further comprises a managing unit, that is:
  • the method comprises:
  • the present invention concerns a DIRCM system and a related method of operation.
  • the DIRCM system according to the present invention is designed to protect a platform (such as land platform or vehicle, an avionic platform, or a naval unit) against infrared-guided missiles, and comprises two or more DIRCM subsystems operable to track and jam IR-guided missiles, wherein said DIRCM subsystems comprise a first DIRCM subsystem and a second DIRCM subsystem, that are installed on the platform so that:
  • the method of operation according to the present invention comprises:
  • the first DIRCM subsystem includes:
  • the second DIRCM subsystem preferably includes:
  • the first tracking and jamming operation preferably includes:
  • the first overlap operation preferably includes starting:
  • the first handover operation includes:
  • the first laser beam is modulated according to a first jamming code
  • the first overlap operation includes starting emitting a second laser beam that is modulated according to said first jamming code and is synchronized with said first laser beam.
  • the first overlap operation is carried out only if the second DIRCM subsystem is not countering any missile.
  • the method of operation further comprises:
  • the method of operation further comprises:
  • the second tracking and jamming operation includes:
  • the second overlap operation preferably includes starting:
  • the second handover operation preferably includes:
  • the third laser beam is modulated according to a second jamming code
  • the second overlap operation includes starting emitting a fourth laser beam that is modulated according to said second jamming code and is synchronized with said third laser beam.
  • the second overlap operation is carried out only if the first directed infrared countermeasure subsystem is not countering any missile.
  • the method of operation further comprises:
  • the DIRCM system comprises a managing unit, that is:
  • the managing unit is programmed to operate the DIRCM subsystems on the basis of:
  • Figure 2 shows a block diagram schematically representing a functional architecture of a DIRCM system (denoted as a whole by 2) according to a preferred embodiment of the present invention.
  • the DIRCM system 2 is installed on an aircraft (not shown in Figure 2 ) and comprises:
  • the first DIRCM manager 211 is configured to control operation of the first thermal tracker 212 and of the first laser unit 213, the first thermal tracker 212 (which conveniently includes a respective IR imaging device) is operable to track threats, the first laser unit 213 is operable to generate laser beams used for IR countermeasures, the second DIRCM manager 221 is configured to control operation of the second thermal tracker 222 and of the second laser unit 223, the second thermal tracker 222 (which conveniently includes a respective IR imaging device) is operable to track threats, the second laser unit 223 is operable to generate laser beams used for IR countermeasures, and the SP suite manager 214 is configured to control operation of the whole DIRCM system 2.
  • the SP suite manager 214 is a software-implemented function, which is implemented only in the master DIRCM subsystem 21, and which is in charge of:
  • the designation of the master and slave DIRCM subsystems 21 and 22 is conveniently decided by the SP suite manager 214 on the basis of a current threat scenario provided by the MWS 3 and of a current engagement state of the master and slave DIRCM subsystems 21 and 22.
  • a software-implemented, reprogrammable table is preferably used, where it is possible to define any threat scenario and any engagement state considered of interest, along with the corresponding designation commands for the master and slave DIRCM subsystems 21 and 22 (i.e., for the DIRCM turrets).
  • first thermal tracker 212 and the first laser unit 213 are integrated into one and the same first steerable turret (not shown in Figure 2 ), while the second thermal tracker 222 and the second laser unit 223 are integrated into one and the same second steerable turret (not shown in Figure 2 ), wherein said first and second turrets are installed on the aircraft in different positions (for example, they can be conveniently located in the same positions as those of the DIRCM turrets 11 and 12 on the aircraft 1 shown in Figure 1 ).
  • the functions of the second DIRCM manager 221 can be conveniently implemented by a respective electronic control unit integrated into the second steerable turret or installed in another position on the aircraft.
  • the FOR of the DIRCM system 2 is divided into different regions.
  • Figure 3 shows an example of field of regard (FOR) divided into six regions upon the assumption that a twin turret configuration is used for the DIRCM system 2 (such as that one shown in Figure 1 ), wherein a left turret is located on a left side of the aircraft (as the turret 12 shown in Figure 1 ) and a right turret is located on a right side of the aircraft (as the turret 11 shown in Figure 1 ).
  • FOR field of regard
  • the FOR of the DIRCM system 2 includes:
  • the tracking-only turret should, theoretically, keep its laser turned off. But, in this case, with current laser technologies, the laser activation could last tens to hundreds of milliseconds, thereby hindering continuity of the jamming code emission during handover.
  • the laser of the tracking-only turret is turned on, but it is steered away from the target.
  • Figure 4 shows an aircraft (denoted as a whole by 4), which:
  • the missile 5 is countered (i.e., tracked and jammed) by the left DIRCM turret 41 and tracked by the right DIRCM turret 42, while the laser of said right DIRCM turret 42 is aimed away from said missile 5 (specifically, the aiming point of the laser of the tracking-only right DIRCM turret 42 is set outside the laser beam divergence).
  • Figure 4 shows also the jamming laser beam (denoted as 43) that is emitted by the left DIRCM turret 41 and is aimed at the missile 5 to jam the latter, along with the laser beam (denoted as 44) that is emitted by the right DIRCM turret 42 and is not aimed at the missile 5.
  • Figures 5 and 6 show examples of IR pictures captured, respectively, by the right DIRCM turret 42 and the left DIRCM turret 41 (in particular, by the respective IR imaging devices used to track the missile 5) in the scenario shown in Figure 4 .
  • the laser of said right DIRCM turret 42 is on the missile 5 very rapidly only by changing its aiming point.
  • the SP suite manager 214 master unit conveniently commands the jamming code index from which the right DIRCM turret 42 shall start reproducing the jamming code, thereby guaranteeing jamming code continuity during handover.
  • the present invention allows to improve the level of efficacy achievable with DIRCM systems in protecting a generic platform against enemy IR-guided missile attacks.
  • the present invention defines new coordination strategies between DIRCM turrets which enable a multiple turret DIRCM system to be, not only, more effective, but also to gain new features not present in a single DIRCM turret or in current multiple (uncoordinated) turret DIRCM configurations.
  • the present invention allows to:
