Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an air defense system 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 radar devices, a fire unit, a server system that controls them, a data communication line, and the like, and is deployed on a relatively large scale. In recent years, for the purpose of complementing such a large-scale system, an air defense system using a portable SAM with higher mobility or an anti-aircraft gun (gun) has been proposed. The SAM system is positioned as a host system, and portable SAMs and anti-aircraft guns (guns) are positioned as lower systems.
[0003]
By the way, in the existing air defense system, the upper system and the lower system are operated independently of each other. In general, portable SAMs and anti-aircraft guns (guns) do not have equipment such as long-range radars, so in order to strike a target, the target must be searched over a wide range. It tends to take time to discover and capture. The host system has a function of assigning targets to the fire unit, but the host system does not have such a function. For this reason, a serious situation may occur in which a target shot and leaked in the higher system is also shot and leaked in the lower system.
[0004]
For these reasons, it is difficult to say that the lower system is sufficiently fulfilling the complementary role of the upper system, and it is difficult for the air defense system including the lower system to fully exert the ability to attack the target. There is a defect.
[0005]
In addition, there are the following Patent Documents 1 to 3 as a document disclosing the technology related to the air defense system. In Patent Document 1, in a PPI display device that displays information such as a target position and speed from an observation device, target position information, the position and number of remaining bullets of each injection device, and a dividend of the injection device that deals with each target Disclosed is a flying object distribution status display device that enables visual evaluation of flying object distribution in a flying object system by displaying information, a grace time until launching a flying object, and a stage for dealing with a target.
[0006]
Patent Document 2 improves the resilience against threats by giving priority to the intercepting elements that make up the network and allowing the remaining priority elements to have control processing functions. A fire control system is disclosed. In Patent Document 3, there is a system in which a plurality of launch control units are connected to each other via a network, the reliability and reliability of target assignment to each launch control unit is improved, and resistance is given. A distributed flying object launch control system capable of realizing command and control is disclosed.

[Problems to be solved by the invention]
As described above, the conventional air defense system has a problem that it is difficult to say that the host system and the lower system are acting organically, and there is an insufficient air defense performance.
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 capable of improving target capturing performance and reliably hitting a target.
[0011]
[Means for Solving the Problems]
In order to achieve the above object, the present invention provides a host system including a radar device that acquires target information and a flying object launching device, a mobile flying object launching device (such as a portable SAM and an anti-aircraft gun (gun)), and the like.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a system diagram showing an embodiment of an air defense system according to the present invention. This system includes an upper system and a lower system that are connected via a wireless line and can communicate information with each other. The host system is realized as, for example, a SAM system, and a plurality of sensors 11 to 13 that acquire target information such as target position, number, and direction of arrival, a control device 2, and a plurality of launch devices 31 to 34 are connected to a communication line L. Connect to the network via, and configure the shooting network. The lower system includes an anti-aircraft gun (gun) 5 and a portable SAM 6. An operator (not shown) of the anti-aircraft gun (gun) 5 and the portable SAM 6 carries the information terminal 4 assigned individually.
[0014]
FIG. 2 is a functional block diagram showing a main configuration of the control device 2 of FIG. The control device 2 includes a high-frequency processing circuit 21 that realizes wireless communication with a lower system, a communication interface (I / F) unit 22 that performs information communication with a shooting network, and a control unit 23.
[0015]
The control unit 23 includes a notification processing unit 23a and an allocation processing unit 23b. The notification processing unit 23a acquires target information from the sensors 11 to 13, and notifies the information terminal 4 of the acquired target information via a wireless line. The allocation processing unit 23b is based on the position information of each information terminal notified from each information terminal 4, the positions of the launchers 31 to 34 given as known data in advance, and the target information acquired by the sensors 11 to 13. The launchers 31 to 34, the anti-aircraft gun (gun) 5 and the portable SAM 6 are assigned to each of the targets. The result of this allocation is notified to each information terminal 4 by the notification processing unit 23a.
[0016]
FIG. 3 is a functional block diagram showing a main configuration of the information terminal 4 of FIG. The information terminal 4 includes a high frequency processing circuit 41 that realizes wireless communication with the host system, a display unit 42, and a control unit 43.
[0017]
The control unit 43 includes a communication processing unit 43a, a position recognition unit 43b, and a display control unit 43c. The communication processing unit 43a performs control for exchanging various information with the control device 2 via a wireless line. The position recognizing unit 43b autonomously calculates the position information of the own terminal by using, for example, a GPS (Global Positioning System) not shown. For example, the calculated position information is periodically notified to the control device 2 of the host system via a wireless line by the communication processing unit 43a. The display control unit 43c visually displays information notified from the control device 2 via a wireless line and notifies the operator. The information notified from the control device 2 includes target information or a result of target assignment for the anti-aircraft gun (gun) 5 and the portable SAM 6.
[0018]
FIG. 4 is a diagram schematically showing information exchanged between the control device of FIG. 1 and the information terminal 4. In FIG. 4, target information is notified from the control device 2 to the information terminal 4. The information terminal processes the target information and displays the air defense information or the received target information on the display unit 42 by symbol display or digital numerical value. Depending on the degree of urgency of the situation indicated in the target information, a message such as “being alert” is also displayed.
[0019]
The location information of the information terminal 4 is notified from the information terminal 4 to the control device 2. In response to this, the control device 2 performs target assignment including the sensors 11 to 13, the anti-aircraft gun (gun) 5, and the portable SAM 6.
[0020]
FIG. 5 is a diagram for explaining the operation of the present embodiment in comparison with the prior art. FIG. 5A shows a situation when the portable SAM 6 is operated alone. Thus, conventionally, since the target approach direction is unknown for the portable SAM 6, it is necessary to search for and deal with the target over a wide range or the entire circumference.
[0021]
FIG. 5B shows a situation when the host system is operated alone. Thus, there is a limit to the radar coverage that each sensor can cope with the target. Therefore, a target arriving from outside the coverage area that can cope with this target cannot be captured, or it takes time to capture, and therefore, the response is delayed.
[0022]
On the other hand, in this embodiment, as shown in FIG. 5C, by connecting the upper system and the lower system via a wireless line, target information (position, speed, identification) acquired by the upper system. Information etc.) is notified to the lower system. Furthermore, it is possible to assign a coverage to be dealt with from the upper system to the lower system. That is, the coverage which is insufficient only by the upper system can be supplemented by the lower system, and therefore the target acquisition performance as a whole can be improved.
[0023]
Further, according to the present embodiment, the target information is notified from the host system to the operator of the lower system, so that the operator can specify the target intrusion course in advance. As a result, as compared with FIG. 5A, the search direction of the target can be limited, so that the target can be found at an early stage. Therefore, it becomes possible to take an interception system at an early stage, and a target that is missed by the higher system can be dealt with by the lower system, so that the shooting can be prevented from being missed.
[0024]
In summary, in the present embodiment, the operator of the anti-aircraft gun (gun) 5 or the portable SAM 6 in the lower system carries the information terminal 4 and connects the control device 2 and the information terminal 4 via a wireless line. By doing so, the upper system and the lower system are connected. The target information obtained by the host system is notified to the information terminal 4, and the direction of arrival of the target, the number of targets, and the like are visually displayed on the display of the information terminal 4.
[0025]
In addition, autonomous positioning means such as GPS is mounted on the information terminal 4, and the acquired position information of the terminal is notified to the control device 2 via a wireless line. The control device 2 considers the position information of each information terminal 4 together with the positions of the launch devices 31 to 34, and determines target allocation including the anti-aircraft gun (gun) 5 and the portable SAM 6 in the launch devices 31 to 34. The result is notified to the information terminal 4 so that the operator of the anti-aircraft gun (gun) 5 or the portable SAM 6 recognizes the target that he / she should be responsible for.
[0026]
With the above configuration, it is possible to cause the host system and the lower system to operate organically with each other and to complement the host system more closely by the lower system. Therefore, it is possible to provide an air defense system that can improve the target capturing performance and can reliably hit the target.
[0027]
