Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an air defense system and an air defense method applied to, for example, an air defense flying object system for a short distance.
[0002]
[Prior art]
One known air defense system is the SAM (Surface to Air Missile) system. This type of system includes a plurality of fire units (hereinafter referred to as FU), a server system that supervises these units, a data communication line, and the like, and is deployed on a relatively large scale. In an air defense system, each FU is often configured to include a shooting (command) control device, a radar device, and a launching device. The launching device includes an anti-aircraft cannon (gun) and a guided bullet launching device.
[0003]
By the way, in this kind of existing system, the critical attack (namely, critical attack sequence) with respect to the critical target is carried out in a closed form within the FU. That is, in each FU, the target to be shot in my area is shot using my device. For this reason, in the existing air defense system, when my launching device fails or the remaining number of bullets becomes 0, it is impossible to deal with the target of fire and there is a possibility that the target of fire is shot and leaked.
[0004]
A related technique is disclosed in Patent Document 1 below. This document does not control multiple FUs by centralized management, but realizes command and control with resistance by allowing each FU to perform processing to achieve overall controlled operations. A networked striking device is disclosed that can be made.

[0006]
[Problems to be solved by the invention]
As described above, since the conventional air defense system is implemented in such a manner that the fire-fighting sequence is closed to individual FUs, there is a possibility that a fire target will be leaked.
The present invention has been made in view of the above circumstances, and an object of the present invention is to provide an air defense system and an air defense method that reduce the possibility of a target being shot and thereby improve the air defense capability.
[0007]
[Means for Solving the Problems]
In order to achieve the above object, an air defense system according to the present invention includes first and second shooting units (for example, FU) each having a plurality of shooting devices (for example, missile launching devices) as information communication lines (for example, shooting networks). In the air defense system connected through the first air defense unit, the first air unit is defined by a first air defense capability determination unit that determines my air defense capability against a target to be attacked, and the first air defense capability determination unit defines the air defense capability of the first air unit. When it is determined that the level is below the level, a request processing unit that requests the second shooting unit to acquire control right of the shooting device provided in the second shooting unit via the information communication line, and according to the request And an intercepting processing unit that intercepts the target subject using the firing device to which the control right is delegated from the second unit of fire. When the second air defense capability determination unit that determines the air capability and the acquisition of the control right are requested from the first shooting unit, the self is within the allowable range of the air defense capability determined by the second air defense capability determination unit. And a delegation processing unit for delegating the control right of the shooting device to the first shooting unit.
[0008]
By taking such measures, when the need for interception occurs due to the entry of an enemy aircraft into the air defense area of the first FU, the air defense capability of the first FU is determined by the first air defense capability determination unit. The When the number of remaining bullets is smaller than the number of enemy aircraft, or when the shooting device is out of order, the first FU is weakened and it is determined that the air defense capability is below a specified level. Then, the control right of the shooting device in the second FU is delegated to the first FU . As a result, the first FU was weakened, it becomes possible to intercept interception subject using shooting device of the first FU. Therefore, it is possible to reduce the possibility of the target being shot and leak, and to improve the air defense capability.
[0009]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is a system configuration diagram showing an embodiment of an air defense system according to the present invention. The air defense system of FIG. 1 includes a plurality of FUs 11 and a shooting network 13 that connects these FUs 11 and enables mutual exchange of information. Each FU 11 includes a missile launcher 11a realized as an anti-aircraft gun (gun), a guided bullet launcher, and the like, a fire control system (FCS: Fire Control System) 11b for comprehensively controlling each missile launcher 11a, And a radar 11c that acquires information related to the target to be attacked.
[0010]
Each FU is assigned an air defense area corresponding to a predetermined air area in advance, and each FU has its own air defense capability within the air defense area. The FCS 11b performs processing such as target assignment to the missile launcher 11a based on target information acquired by the radar 11c and various information notified from other FUs.
[0011]
FIG. 2 is a functional block diagram illustrating a configuration example of the FCS 11b of FIG. The FCS 11 b includes a communication interface (I / F) unit 21, a control unit 22, and a communication processing unit 23. The communication interface (I / F) unit 21 performs information communication between the shooting network 13 and the control unit 22. The communication processing unit 23 is responsible for information communication between the missile launching device 11 a and the control unit 22. In particular, in this embodiment, the communication interface unit 21 transmits my FU's critical calculation data to other FUs in real time via the shooting network 13.
[0012]
The control unit 22 includes an air defense capability determination processing unit 22a, a control right acquisition processing unit 22b, and an interception processing unit 22c. The air defense capability determination processing unit 22a determines my air defense capability based on the remaining number of bullets of the missile launcher 11a and the presence / absence of a failure when an enemy aircraft enters the air defense area assigned to itself. The control right acquisition processing unit 22b detects missiles provided in other FUs when the air defense capability for the target to be attacked is below a predetermined level, that is, when the air defense capability determination processing unit 22a determines that the air defense capability for the target is not sufficient. The control right of the launching device 11a is acquired via the shooting network 13. The interception processing unit 22c intercepts the critical target using the missile launcher 11a that has acquired the control right.
[0013]
FIG. 3 is a schematic diagram for explaining the operation of the air defense system having the above configuration. In FIG. 3, the FUs 100 and 200 that respectively develop the air defense areas are connected to each other via the shooting network 13. Assume that the missile launchers 11a belonging to the FUs 100 and 200 mount a total of eight missiles.
[0014]
In this state, it is assumed that the first wave attack by eight attack aircraft from the enemy side is performed on the air defense area of the FU 100. Then, the FU 100 will mobilize each missile launcher 11a and confront the enemy aircraft. Therefore, all 8 missiles are consumed.
[0015]
It is assumed that the second wave attack is further started from this state, and four enemy aircrafts arrive in the air defense region of FU 100 and four enemy aircrafts arrive in the air defense region of FU 200, respectively. In this case, in the FU 100, all missiles are shot out and the air defense capability is lost. The control unit 22 of the FU 100 determines that, and sends a request message to the FU 200 indicating that it wants to acquire the control right of the missile launcher 11a.
[0016]
Upon receiving the request message, the FU 200 recognizes its own air defense capability, and if the control right can be delegated, returns message information to the FU 100 that the control right is accepted. When this is received by the FU 100, the control right of some of the missile launchers 11a in the FU 200 is immediately transferred to the FCS of the FU 100. This is schematically shown by a dotted line in the figure.
[0017]
As a result, the FU 100 can confront the second wave attack with four missiles, and the FU 200 can confront with the four missiles. Accordingly, sufficient air defense capability can be exhibited by the two FUs 100 and 200 even for the second wave attack, and the possibility that enemy aircraft will be shot and leaked can be reduced.
[0018]
FIG. 4 is a schematic diagram showing a case where the entire azimuth is protected by four FUs 100 to 400. FIG. 4 shows a case where the entire circumference of the VA is protected by the FUs 100 to 400 that develop the air defense regions in the 90 ° azimuth of each VA (important facility) arranged in the center.
[0019]
FIG. 5 is a diagram showing a state in which a critical target is shot and leaked in the system configuration of FIG. Thus, for example, if an enemy aircraft is shot and leaked in the FU 200, the enemy aircraft may enter the air defense area of the FU 100 or the like.
[0020]
FIG. 6 is a diagram for explaining a situation that can occur when shooting and leakage occur. When an enemy aircraft enters the air defense area of FU100, if the LAU (missile launcher) fails or the remaining number of bullets of FU100 is 0, the air defense capability of FU100 is lost and The interception cannot be carried out.
[0021]
On the other hand, in the present embodiment, an information communication path between FUs is formed via the shooting network 13, and an environment for realizing an inter-FU connection function is provided. Then, the critical calculation data in each FU is transmitted to other FUs in real time. When it is necessary to intercept the target to be attacked from this state, my air defense capability is determined in each FU. As a result, when it is determined that the air defense capability is not satisfied even though the intercepting process is necessary, the control right of the missile launcher 11a belonging to another FU is acquired, and the missile launcher 11a is borrowed so to speak. In this way, you can intercept the target.
[0022]
As described above, even when the remaining number of bullets of the FU that needs to be intercepted is 0, or when the missile launcher 11a is out of order, the missile launcher 11a of another FU capable of firing the target to be attacked is used. It can be used to deal with the target. Accordingly, it is possible to hit the target to be hit that has been hit and leaked conventionally, and to improve the air defense capability as the air defense system. For this reason, it is possible to reduce the possibility of the target being shot and leak, thus providing an air defense system and an air defense method with an improved air defense capability.
[0023]
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 components disclosed in the embodiment. For example, some components may be deleted from all the components shown in the embodiment.
