Description

  The present invention relates to an air defense system.

For example, systems disclosed in Patent Documents 1 and 2 below are known as air defense systems. In general, an air defense system includes a sensor that detects an invading target. However, the target information acquired by the sensor is generally used in a closed form for a specific air defense system. In other words, existing air defense systems perform air defense against threat targets based on target information obtained from sensors for each system. For this reason, depending on the air defense system, the target information obtained by its own sensor is not sufficient, and there are situations where preparation time and critical time until a threat target is required are lost and cannot be dealt with. This is a weak point and a blind spot in defense, and it is a good invasion point for the invaders.

As described above, in the existing air defense system, information transmission between the individual systems is insufficient, and there is a possibility that a blind spot for defense may be generated.
The present invention has been made under the circumstances described above, and an object of the present invention is to provide an air defense system that integrates a plurality of air defense systems and strengthens the response to threat targets beyond the boundaries of affiliation / jurisdiction / system.

  In order to achieve the above object, according to one aspect of the present invention, there is provided a sensor for acquiring target information, a single or a plurality of air defense units for performing air defense measures against a threat, and a communication environment between the sensor and the air defense unit. Forming communication means; means for collecting the target information acquired by the sensor via the communication means; means for integrating the collected target information to generate integrated target information usable over the air defense unit; An air defense system comprising: means for assigning a target to the air defense unit based on the integrated target information; and means for notifying the assigned air target to the air defense unit via the communication means. Is provided.

  By taking such means, integrated target information is created based on target information acquired by a plurality of sensors such as various airborne sensors and sensors installed on the ground. That is, the target information is merged. The integrated target information thus obtained is transmitted in units of air defense by communication means such as a high-speed data link. Moreover, target assignment to air defense units is performed based on the integrated target information. From these facts, it is possible to construct an air defense system with a wider area than before, and to deal with a target that has taken a long time before the hit.

  According to the present invention, it is possible to provide an air defense system that integrates a plurality of air defense systems and strengthens the response to threat targets beyond the affiliation / jurisdiction / system frame.

  FIG. 1 is a conceptual diagram showing an embodiment of an air defense system according to the present invention. This system is formed for the purpose of regional defense against invading cruise missiles and aircraft, for example. In this system, an airborne sensor 1, a ground-mounted sensor 2, and an anti-air firearm 3 are connected via a high-speed data link 20 to form a network FCS (Fire Control System).

  Among these, the airborne sensor 1 includes an aircraft, a drone 4, a balloon radar 5, and the like equipped with a sensor capable of detecting and following an invading threat. These are typically placed (deployed) on the forefront defense line and used to initially detect the invasion target. The ground installation sensor 2 includes a ground radar 8 configured by mounting a radar system on a vehicle. The anti-aircraft 3 includes a missile-mounted UAV 6, various SAM systems (including a portable SAM system) 7 deployed on the ground, or a vehicle 10.

In FIG. 1, integrated target information is created based on target information from each sensor such as an airborne sensor 1 and a ground-mounted sensor 2. Then, based on this integrated target information, target assignment is performed to the optimum firearm among the anti-aircraft firearms 3 connected to the network FCS, and the threat target is dealt with.
The network FCS in FIG. 1 can also have a dedicated laser, sensor, or launcher. Further, the network FCS may acquire target information from an airborne sensor, a ground-mounted sensor 2, or a sensor device on a satellite orbit.

  FIG. 2 is a conceptual diagram showing details of the air defense system of FIG. On the ground, among the networks FCS 14 and 16, the SAM system 1 and the SAM system 2 belonging to the land command and control system 11, the networks FCS 14 and 16, the UAV control device 12, and the balloon radar processing device 13 are connected via the high-speed data link 20. Build a mutual communication environment. The UAV (Unmanned Aerial Vehicle) 6 is equipped with a small missile to deal with the invading FB (Fighter Bomber) and CM (Cruse Missile).

  The UAV control device 12 controls the UAV 6 by remote control, and intercepts invading threat targets such as FB and CM by missiles. In particular, when guiding a missile from the network FCS 14, the high-speed data link 20 is used to transmit information such as a target and a position. The balloon radar processing device 13 gives an instruction to the MSL from the balloon radar antenna 15 via the data link.

  By constructing such a system, it is possible to unify the information of the dedicated sensors that each air defense unit has individually, fuse independent air defense systems, assign targets to the optimal air defense firearms, It is possible to deal with invading threat targets such as commercials. For example, threat targets can be dealt with based on target information from various dedicated sensors used in air defense systems such as various SAM systems deployed on the ground.

  Also, based on target information from various aerial sensors, airborne sensors, and other dedicated sensors in other air defense systems, target information, target allocation, etc., can be assigned to various SAM systems (such as portable SAM systems) deployed on the ground. The air defense system can intercept the target according to the target allocation instruction (information).

  In addition, a function for connecting various anti-aircraft systems, a function for guiding a UAV equipped with a missile, and the like are realized via the high-speed data link 20 and the like. Therefore, based on target information from various sensors, the network-type FCS conducts command and control such as optimal thermal power allocation and target allocation for connected anti-aircraft firearms, so that sensors with different affiliations / jurisdictions It is possible to construct a complex air defense system using systems and anti-aircraft weapons.

  With such a system, it is possible to construct an air defense system that can respond / respond faster, more efficiently, and more accurately than a conventional air defense system that can obtain only limited target information. It becomes possible. Furthermore, by building such a system, it is possible to reduce the vulnerable parts of domestic air defense systems.

  Note that the present invention is not limited to the above-described embodiment as it is, and can be embodied by modifying the constituent elements without departing from the scope of the invention in the implementation stage. In addition, various inventions can be formed by appropriately combining a plurality of constituent elements disclosed in the embodiment. For example, some components may be deleted from all the components shown in the embodiment, or some components may be added to all the components.
