Definitions

  • the present disclosed subject matter is concerned with defense systems and more specifically with active protection systems.
  • An active protection system is related to protection systems which actively prevent sensor-based or other incoming threats from acquiring and/or destroying a target.
  • the active protection system can protect soldiers, vehicles, buildings, military base and other platforms from large variety of threats.
  • Electronic countermeasures that alter the electromagnetic, acoustic or other signature(s) of a target thereby altering the tracking and sensing behavior of an incoming threat are designated soft kill measures.
  • the hard kill measures generally refer to measures taken in the so-called "end-game" shortly before a warhead/missile hits its target.
  • the hard kill measure in general physically affects the incoming warhead/missile by means of either blast and/or fragment action.
  • the active protection system using a hard kill measure, is operated by detecting the incoming threat and killing it before it hits the target. The detection of the coming threats can be based on radar detection systems that provide information related to the incoming threat.
  • the killing interception of one type interception systems can occur at a far distance from the target, for example, between 10 to 100 meter.
  • the killing interception of another type of interception system can occur close to the target's wall, for example, at a distance of between 1 to 5 meter.
  • Each type of the hard killing interception systems has benefits and limitations regarding the cultural damage, the impact on the target, the protection threats level, the cost, the killing probability, reliability, weight and more.
  • US 2012/0217301 A1 describes a system to track a threat and determine a countermeasure to counter the threat.
  • US 2011/0127328 A1 describes a system for dual-band detection of incoming threats.
  • EP 2338022 B1 describes a system and method for protecting an enclosure against attack of projectiles.
  • VALPOLINI P "Active Armour Protection", ARMADA INTERNATIONAL, ZURICH, CH, vol. 34, no. 3, 1 June 2010 describes protection systems that sense and counter incoming projectiles.
  • the background of the present invention concerns an active protection system for protecting a platform from an incoming threat.
  • the active protection system comprises:
  • the existence of two types of countermeasure arrangements, i.e., the first and the second countermeasure arrangements, within one active protection system allows this system to intercept a much wider variety of types of threats as opposed to the case, where only one of these countermeasure arrangements is used in an active protection system.
  • the first countermeasure arrangement constitutes a first layer of active protection
  • the second countermeasure arrangement constitutes a second layer of active protection.
  • the active protection system of the presently disclosed subject matter can provide protection in a wide variety of combat scenarios such as: urban warfare, open terrain warfare, and rural areas.
  • the present invention in accordance with one aspect and as defined in independent claim 1, provides a system for detecting an incoming threat, comprising:
  • the analysis of the output data from said RF system can include application of pattern recognition techniques.
  • the output data from the RF system comprises data can be related to electromagnetic pulse associated with the engine ignition of the incoming threat.
  • the analysis of the output data from said RF system can further comprise performance of spectral analysis of the electromagnetic pulse.
  • the present invention in accordance with another aspect and as defined in independent claim 3, provides a method for detecting an incoming threat, comprising:
  • the step of analyzing the output data from said RF system can comprise a step of applying pattern recognition techniques.
  • the output data from the RF system can comprise data related to electromagnetic pulse associated with the engine ignition of the incoming threat.
  • the step of analyzing the output data from said RF system can further comprise performing spectral analysis of the electromagnetic pulse.
  • the spectral analysis can include analysis in two bands: a high band of frequencies and a low band of frequencies.
  • the method can further comprise a step of analyzing, by said controlling unit, said output data from the RF system for tracking the incoming threat.
  • the method can further comprise a step of analyzing, by said controlling unit, said output data from the radar system for determining the type of the incoming threat.
  • FIGs. 1A and 1B of the drawings schematically illustrates two examples of platforms in form of armored personnel carriers 10 and 20, each having a known in the art countermeasure arrangement mounted thereto.
  • the armored personnel carrier 10 of Fig. 1A has a countermeasure arrangement 12 which is configured to intercept an incoming threat at a near interception point, i.e., at a location which is proximal to the walls of the armored personnel carrier 10.
  • the countermeasure arrangement 12 is related to the "on the wall” countermeasure arrangements which intercept the incoming threat as close as possible to the walls of the armored personnel carrier.
  • the principle behind the operation of the "on the wall” countermeasure arrangements is that as close to the platform the interception is performed, the collateral damage that is caused to the platform's surrounding is reduced.
  • One example of the countermeasure arrangement 12 is the 'Iron Curtain' system available by Artis, LLC. This system is described, for example, in US patent 7,684,020 .
  • the countermeasure arrangement 12 can be used in short range combat scenarios, e.g., urban scenarios, and against incoming threat such as ATGM, EFP, Long rods and Tandem.
  • the armored personnel carrier 20 of Fig. 1B includes another type a countermeasure arrangement 22 which is configured to intercept an incoming threat at a far interception point, i.e., at a location which is not proximal to the walls of the armored personnel carrier 20.
  • the countermeasure arrangement 22 is related to the "long distance" type of countermeasure arrangements which intercept the incoming threat in the air, at a distance which is not proximal to the armored personnel carrier 20.
  • the countermeasure arrangement 22 can be suitable for use in combat scenarios such as open field warfare.
  • the countermeasure arrangement 22 has an ability to encounter and intercept a large variety of threats, such as small and large missiles, and other types of serious threats. It is known that the collateral damage that can be caused by the countermeasure arrangement 22 is greater than the collateral damage that can be caused by the countermeasure arrangement 12.
  • One example of the countermeasure arrangement 22 is the "fire wall" system available by Metal Storm Limited, Brisbane (AU).
