Abstract

PURPOSE:To maximize a general target hitting rate by effectively utilizing a gun by automatically obtaining information of exactly judging a shooting timing of the gun after a missile attack to a target such as an antiship missile, etc., and increasing an opportunity of attacking as much as possible in a weapon controller for controlling an on-board missile and the gun. CONSTITUTION:A gun shoot limit deciding unit 11 compares a time to an intercept after a missile is launched from a missile shoot calculator 6 with a flying time of a cannonball to a target from a gun shoot calculator 8 to limit shooting of the gun to a gun shoot sequence controller 9, and displays to a weapon control operation display unit 10. Accordingly, even during missile attacking, since information for exactly judging a gun shooting timing without disturbing it can be automatically obtained, a vertical protection with the missile and the gun can be extremely effectively conducted systematically to a high speed target such as the antiship missile, etc.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a weapon control device for controlling weapons such as missiles and guns.

[0002]

2. Description of the Related Art Short-range or medium-range anti-aircraft missiles, medium-caliber automatic guns, machine guns for close-range defense of own ships, etc. are used as anti-aircraft weapons mounted on ships to protect themselves from threats such as anti-ship missiles To be FIG. 6 is a conceptual diagram of the range of these weapons. In FIG. 6, s is the ship, t is the target, p is the maximum missile range, q is the maximum gun range, and r is the maximum machine gun range. Since these weapons have different range as shown in Fig. 6, they attack with anti-aircraft missiles as the target approaches, and if they fail, they deal with them with a gun, and finally with a machine gun for close-range defense. It is necessary to increase the overall blocking rate against the target by performing so-called defense in depth. Conventionally, one of those which meet such a request is shown in FIGS. 4 and 5. FIG. 4 is an overall configuration diagram of a weapon system including a weapon control device. In FIG. 4, 1 is a missile launcher, 2 is a gun, 3 is a machine gun, 4
Is a weapon control device that has a tracking radar and controls the missile launching device 1, the gun 2, and the machine gun 3. FIG. 5 is a detailed view of the weapon control device 4. In FIG. 5, 5 is a target tracking processing unit for tracking a target by a tracking radar, 6 is a missile shooting calculation unit, 7 is a missile firing sequence control unit, 8 is a gun firing calculation unit, 9 is a gun firing sequence control unit, and 10 is a weapon. It is a control operation display section. The part related to the control of the machine gun 3 is omitted because it is not directly related. Next, the operation of the weapon control device 4 will be described. Target specifications such as the position and speed of the target obtained by the target tracking processing unit 5 are sent to the missile shooting calculation unit 6 and the gun shooting calculation unit 8 to perform shooting calculation. The missile and gun launch specifications obtained here are sent to the missile launcher 1 and the gun 2. The missile launch sequence control unit 7 and the gun launch sequence control unit 9 are based on the combatability evaluation data from the missile shooting calculation unit 6 and the gun shooting calculation unit 8, the status of the missile launcher 1 and the gun 2, and the operation result of the operator. Controls to advance the firing sequence of. Weapon control operation display section 10
Performs operations and displays for missile and gun control.
This weapon control device controls the missile and the gun as described above, but controls the missile and the gun completely independently. For this reason, when the gun is within range during an attack with a missile, it is necessary to judge when to fire the gun from the missile shooting calculation and independent information obtained from the result of the gun shooting calculation. Moreover, since a gun with a firing rate of about several tens of shots / minute is not very effective against a high-speed anti-ship missile, a missile that is a guided weapon and a machine gun with an extremely high firing speed were used to counter anti-ship missiles. . However, in recent years, medium-caliber guns with a firing rate of 100 rounds per minute or more have appeared, and can be used for anti-ship missiles.

[0003]

A conventional weapon control device for controlling a missile and a gun is to control the missile and the gun independently as described above. Therefore, if you try to fire a gun against the same target immediately after launching a missile, you need to determine the firing time of the gun so as not to shoot down the preceding missile, but you can obtain it from the missile firing calculation and the gun firing calculation The operator had to judge from the independent information, and it was not possible to make a quick judgment. The range of short-range missiles and medium-caliber guns largely overlap, and there are many situations where both missiles and guns can attack. In order to make effective use of the gun, it is necessary to have information that can properly judge when the gun is launched so as not to interfere with missile attacks. However, since the conventional weapon control device performs completely independent control as described above, it was not possible to fire the gun at the earliest time after the missile was fired. For this reason, although the gun was able to cope with high-speed anti-ship missiles in terms of performance, it was not possible to effectively use the gun from the perspective of defense in depth with the missile. The present invention has been made to solve the above problems, and provides information on the launch time of a gun that does not interfere with the preceding missile even during a missile attack for a single target, and the missile An object of the present invention is to obtain a weapon control device that appropriately provides the launch timing of a gun as information so that a missile that is attacking the target to which the gun is assigned does not interfere even when coping with multiple targets at the same time. It should be noted that there is no flexibility in automating the firing of guns such that it cannot deal with cases where the tracking situation suddenly deteriorates and the firing angle of the gun becomes unstable. For this reason, the gun firing operation is semi-automatic as described above.

[0004]

In the weapons control device according to the present invention, when the target tracking processing is performed for a single target like a tracking radar, the time Tt from the missile shooting calculation unit to the intercept obtained after the missile is launched. When,
Shell flight time T2 to the target obtained from the gun shooting calculator
And a gun firing restriction determination unit that determines the firing restriction of the gun. When the target tracking process and the missile control are performed for multiple targets, the gun firing restriction unit is used to limit the firing of the gun by the same means as above when a missile attack is being made against the target assigned to the gun. It is a thing.

[0005]

In the gun firing restriction determination unit, the time Tt until the interception of the missile is compared with the flight time T2 of the gun. If Tt is larger than T2, the missile is shot by the missile before the preceding missile intercepts the target. Since it may be dropped, the gun is restricted from firing, and this is displayed and shown to the operator. Also, T2 is T
If it is larger than t, the shell does not shoot down the missile, so that the gun can be fired and the fact that it is displayed to the operator is recommended.
Further, when the target tracking processing is performed for a plurality of targets, the same operation as above is performed when the missile attack is being performed on the target to which the gun is assigned.

[0006]

EXAMPLES Example 1. 1 is a block diagram showing an embodiment of a weapon control device according to the present invention. In FIG. 1, 5 is a target tracking processing unit for tracking a single target by a tracking radar or the like, 6 is a missile shooting calculation unit, 7 is a missile launch sequence control unit,
8 is a gun firing calculation unit, 9 is a gun firing sequence control unit, 10
Is a weapon control operation display unit, and 11 is a gun firing limit determination unit that determines the firing limit of a gun so as not to shoot down a preceding missile when a missile is attacking the same target.
Next, the operation will be described. In FIG. 1, the parameters such as the position and speed of the target obtained by the target tracking processing unit 5 are sent to the missile shooting calculation unit 6 where the shooting calculation for launching the missile is performed. This provides specifications such as the predicted hit point, the flight time Tm2 of the missile up to the predicted hit point, and the time Tt until the missile intercepts after the missile is launched. Other orders for controlling the missile launcher are calculated. Further, the above-mentioned target specifications are also sent to the gun shooting calculation unit 8 where the shooting calculation for gun shooting is performed. As a result, the predicted hit point of the gun, the flight time T2 of the shell until the predicted hit point, and the gun order are calculated. The missile launch sequence control unit 7 controls the progress of the launch sequence based on the status of the missile launching device and the missile and the operation of the operator. Similarly, the gun firing sequence control unit 9 advances the gun firing sequence based on the gun status and operator's operation. Gun firing restriction determination unit 11
If there is a missile attack on the target currently being tracked,
Before the missile intercepts the target, it makes a decision to limit the firing of the gun so that it cannot be shot down by the shell. FIG. 3 shows the relationship between the target, the missile, and the ammunition when the missile and the gun attack one target approaching the own ship. Where a, b and c
The three figures are comparisons when the time from the missile launch to the gun launch is changed. Since the initial velocity of a medium-caliber shell, that is, the speed of the shell when it is launched, is higher than the speed of the missile, it overtakes the missile. Because of this, the shell may shoot down the preceding missile, but it shows the time relationship between them. In FIG. 3 (a), after the missile is launched at t0, Tt from the missile firing calculation unit and T2 from the gun firing calculation unit are compared, and when the gun is fired while Tt> T2 is satisfied, the missile is targeted. The shell will overtake the missile before intercepting it. In FIG. 3B, when Tt = T2 after the missile is launched and the gun is launched at the same time, the missile and the shell simultaneously intercept the target. Figure 3
When the gun is fired at Tt <T2 after the missile is fired in (c), the missile intercepts the target and then the ammunition intercepts. Therefore, the shell does not prevent the missile from attacking. The gun firing restriction determination unit 11 compares Tt from the missile firing calculation unit 6 after the missile launch with T2 from the gun firing calculation unit 8. If Tt ≧ T2, the gun firing sequence control unit 9 is prohibited from firing. If Tt <T2, the firing prohibition is released. Further, on the weapon control operation display unit 10, if Tt ≧ T2, gun firing prohibition is displayed, and if Tt <T2, gun firing is recommended to be recommended.

Example 2. FIG. 2 is a block diagram showing another embodiment of the weapon control device according to the present invention. 5 in FIG.
Reference numeral a is a multi-target tracking processing unit for tracking a plurality of targets by a phased array radar or the like, and reference numeral 5b is a target tracking processing unit for tracking a single target by a tracking radar or the like, which calculates target specifications for performing gun shooting calculation. It is for. Reference numeral 5c is an engagement management unit for selecting a target to be fired by a missile from the targets to be tracked by the multi-target tracking processing unit 5a and selecting a target for gun allocation. 6a is the battle management unit 5
It is a missile shooting calculation unit that performs missile shooting calculation for a plurality of targets selected by c. Others 7 to 11 are the same as in the first embodiment. Next, the operation will be described. The engagement management unit 5c selects a target to be missile-attacked from the plurality of targets tracked by the multiple-target tracking processing unit 5a. The missile shooting calculation unit 6a performs missile shooting calculation for a plurality of targets based on this. Engagement Management Department 5
The c also selects a target to be attacked by the gun from the targets instructing the missile attack. As a result, the target information is sent from the multiple target tracking processing unit 5a to the target tracking processing unit 5b, the target tracking processing unit 5b performs tracking, and the gun shooting calculation unit 8 performs gun shooting calculation based on the specifications obtained from this. Here, the target specifications obtained by the multiple target tracking processing unit 5a have the accuracy for missile shooting, but the target shooting processing unit 5b has the accuracy because the gun shooting calculation is insufficient in accuracy.
The gun firing restriction determination unit 11 inputs T2 from the gun shooting calculation unit 8 and Tt for the target for which the gun shooting calculation is performed from the missile shooting calculation unit 6a, and compares them, and Tt ≧ T2
If so, prohibit firing to the gun firing sequence control unit 9,
If Tt <T2, the firing prohibition is released. Further, on the weapon control operation display unit 10, if Tt ≧ T2, gun firing prohibition is displayed, and if Tt <T2, gun firing is recommended.

[0008]

As described above, the present invention automatically obtains information that can properly judge the timing of a gun launch that does not hinder a missile attack even during a missile attack. The effect is that defense can be implemented very effectively. In addition, even when the missile attack is performed on a plurality of targets, similarly, information that can properly judge the firing time of the gun is automatically obtained, so that there is an effect that the defense in depth can be effectively performed against the plurality of targets.
