Abstract

<P>PROBLEM TO BE SOLVED: To provide an air defense system reinforced in a countermeasure to a threat target. <P>SOLUTION: This air defense system is constituted by loading a compact missile 20 capable of coping with an FB (Fighter Bomber) and a CM (Cruse Missile), on a UAV (unmanned Aerial Vehicle) 10. This system is generally put (equipped) on a defense line of a front line, and wirelessly remote-controls the UAV on the basis of target information from various aerial sensors such as a sensor-carrying aircraft and the like for the initial detection of an invading target. The missile loaded on the UAV attacks the threat target such as invading FBs, CMs and the like. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

  The present invention relates to an air defense system.

For example, systems disclosed in Patent Documents 1 and 2 below are known as unmanned aircraft systems. When scouting enemy territory in an air defense system, manned aircraft are highly dangerous to pilots and the like, and therefore it is considered to use unmanned aircraft called UAV (Unmanned Aerial Vehicle).
JP 2005-28935 A Japanese Patent Laid-Open No. 2005-82018

When intercepting FB (Fighter Bomber), CM (Cruse Missile), etc. invading at an early stage on the ocean, perform FI (Fighter Intercept) from the air base or CAP (Combat Air Patrol) on the ocean. It is common to conduct air defense operations with existing FIs or offshore ships. In the case of such an air defense system, it cannot be said that it is a sufficient defensive measure to defend Japan, and Japan's defense is considered insufficient.
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 with enhanced response to threat targets.

  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, and an unmanned aerial vehicle belonging to one of the plurality of air defense units and having a flying object, the unmanned aircraft via the communication means based on the target information acquired by the sensor An air defense system is provided which is steered and intercepts a threat target by the flying object.

  By taking such measures, for example, a UAV equipped with a missile can cope with invading FBs and CMs based on target information from various sensors. Accordingly, it is possible to respond / respond to the invasion target further away than the air defense area of the conventional air defense system that can obtain only limited target information.

  According to the present invention, it is possible to provide an air defense system with enhanced response to a threat target.

  FIG. 1 is a system diagram showing an embodiment of an air defense system according to the present invention. This system is for example designed for regional defense against cruise missiles. In this system, an air defense system such as a SAM system deployed on the ground is linked via a platform such as an airship 100. Each air defense system has sensors and performs air defense measures against threats.

  In some cases, the target information related to the invasion target such as FB1, CM2, etc., which comes from a long distance, may not be obtained with only the sensor of the system itself provided in each air defense system. Therefore, in each air defense system, only limited target information can be obtained, and the response to the threat target may be delayed. Therefore, in this embodiment, the target information from each sensor is distributed and transmitted to the air defense system deployed on the ground via the information transmission type relay airship 100, so that it is difficult to deal with threat targets so far. On the other hand, it explains that it becomes possible to cope with it.

  By the way, the system of FIG. 1 is provided with a UAV (Aerial UAV, High Speed UAV) 10 equipped with a small missile capable of dealing with FB1 and CM2. Then, integrate target information from various sensors deployed on the forefront of the defense line, such as sensor-equipped aircraft, sensors deployed on the ground, etc. Guide quickly. Furthermore, the invasion target is intercepted by a missile mounted on the UAV10. As a result, it is possible to realize an air defense system that can deal with threat targets for which sufficient time cannot be secured with existing technology.

  FIG. 2 is a conceptual diagram showing a UAV used in the system of FIG. The UAV 10 includes a light aircraft, a glider, and the like equipped with a remote control mechanism, and is operated by radio from above or from the ground via a ground side system or an information transmission type airship or aircraft. Furthermore, this UAV 10 is equipped with a small missile 20 and can intercept threat targets such as FB and CM that are invading.

  As described above, in this embodiment, a small missile capable of dealing with FB (Fighter Bomber) and CM (Cruse Missile) is mounted on a UAV (Unmanned Aerial Vehicle). In general, the UAV is remotely operated by radio based on target information from various aerial sensors such as a sensor-equipped aircraft that is arranged (deployed) on the forefront defense line and initially detects an invasion target. Then, the invading FB, CM and other threat targets are intercepted by missiles installed in the UAV. As a result, the threat target can be dealt with / addressed from a farther position than the existing air defense system.

  In this way, for existing air defense systems and components that can only obtain information from limited sensors, target information from other than its own system is obtained for threat targets such as invading FBs and CMs. On the other hand, by using a UAV equipped with a small missile as part of an air defense system, it is possible to respond / treat faster, more efficiently and more accurately. Moreover, it becomes possible to reduce the weak part in a Japanese air defense system using such a system.

  That is, as in this embodiment, the information of dedicated sensors held in each air defense unit is unified, and a UAV equipped with a small missile capable of dealing with CM, FB, etc. is guided to the invasion target, and FB, CM, etc. Air defense that can respond / respond faster, more efficiently and more accurately than traditional air defense systems that can only obtain limited target information by dealing with the invading threat target It becomes possible to construct a system. Furthermore, by building such a system, it is possible to reduce the fragile parts of Japan's air defense system.

  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 some components shown in the embodiment, or some components may be added.
