Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an anti-aircraft weapon allocation device, and in particular, in a combat command system, a plurality of anti-aircraft weapons that can specify a plurality of targets, and a plurality of anti-aircraft weapons that can assign a plurality of anti-aircraft weapons. Anti-aircraft weapons allocation device for determining effective combinations with targets.

[Conventional technology]

Traditionally, in combat command systems, the assignment of anti-aircraft weapons, which determines which anti-aircraft weapons should fire which targets, has been based on a one-to-one correspondence that specifies only one target for each anti-aircraft weapon. (For example, the patent application in 1986)
-25971 specification).

However, with the increase in airborne threats, the performance of anti-aircraft weapons has improved, making it possible to attack multiple targets with a single anti-aircraft weapon. In the conventional technology described above, the circuit specifies one target combination for μ1 anti-aircraft firearms, so in order to specify multiple targets (including targets of the same type) with one anti-aircraft firearm, , the number of targets specified for the anti-aircraft weapon (the number of targets that can be assigned to that anti-aircraft weapon) is calculated through the same circuit, and the target corresponding to the anti-aircraft weapon is determined from the result, resulting in 91 targets. Sometimes multiple anti-aircraft weapons were assigned to them.

[Problem that the invention seeks to solve]

The problem of the prior art that the present invention aims to solve is that when assigning a target to one anti-aircraft weapon, it takes time to pass through the calculation circuit for the specified number of targets, and as a result, This is especially true when multiple anti-aircraft weapons are assigned. SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide an anti-aircraft weapon assignment device that solves the above-mentioned problems.

〔Example〕

Next, the present invention will be described in detail with reference to drawings showing embodiments.

Fig. 1 is a block diagram showing the configuration of an embodiment of the present invention, Fig. 2 is an explanatory diagram of calculating the threat level for a target for an anti-aircraft firearm, and Fig. 3 is an explanation for calculating the threat level for each target for each anti-aircraft firearm. 4(a) to 4(e) are explanatory diagrams showing the operation corresponding to the configuration of this embodiment, and FIG. 5(a) to
(c) is an explanatory diagram showing the overall operation of this embodiment.

First, an overview of the present invention will be explained.

Target Ta (generally Tl~T,
) with a firearm Ft (generally Fl-F)l), which anti-aircraft weapon F8 attacks which target T,
It must be determined whether it is appropriate to allocate Therefore, target information such as the distance and direction to the flying object or the number of targets confirmed by radar or visual observation,
The threat level C of the anti-aircraft firearm Ft against the target T is calculated by inputting the anti-aircraft firearm information such as the position, direction, number of bullets remaining, and whether or not it is ready to fire.

Looking at Figure 2, we can see that the distance between the anti-aircraft weapon F and the target 11N is R8, and the target TI is moving at a speed v11.
The direction of anti-aircraft firearm F1 as seen from the angle 017% anti-aircraft firearm F
When the state of , is Sl, a constant, the threat level CIJ of target T, against anti-aircraft weapon F1 is - Generally speaking, anti-aircraft firearm F1
It is approximately inversely proportional to the distance R1J from the reach distance, and if the anti-aircraft weapon F and the target T are opposite, the maximum
If it points away from the firearm F, then it can be considered to be the minimum, and the speed of the target T, ■1. The larger the value, the greater the impact. Therefore, the threat level CIJ is expressed, for example, by equations (1) and (2), and the larger the value, the higher the threat level.

When 0°≦θIJ≦90°, CIJ = k (VtJ/RIJ) (1+cos

・(21 Here, the threat level C is calculated for each combination between targets T1 to T, = T, and anti-aircraft weapons Fl-J″X to F.
Il~CtJ~CM is determined. This threat level calculation can be considered to be an approximate formula due to the setting of formula (1), so
The value of the peak l is quantized to simplify subsequent calculation processing.

Then anti-aircraft weapon F! It is possible to create a matrix in which each row corresponds to the target T and each column (see the matrix in FIG. 3).

The egg weight of the designated number of targets for each anti-aircraft firearm is compared with the sum of the assigned number of anti-aircraft firearms for each target, and the one that takes the smaller value is used as the selection criterion.

The following description will be made assuming 1<b. The order in which combinations of anti-aircraft weapons and targets are determined is based on the threat level of the weapon that has the largest difference between the maximum value and the second value of the threat levels from multiple targets for one anti-aircraft weapon. Determine based on the combination with the maximum goal. Each time this combination is determined, the number of designated targets for the anti-aircraft firearm and the number of assigned anti-aircraft firearms for the target decrease by f11. Furthermore, the number of designated targets for anti-aircraft weapons is a! When becomes O, that line is the target anti-aircraft weapon allocation number b! When becomes O, the threat level CxJ in that column has no meaning and all values become 0. The method described above is repeated until at least one of the designated target number of anti-aircraft firearms 81 and the target assigned number of anti-aircraft firearms b7 is OK. Determine the combination of anti-aircraft weapons and targets accordingly.

Next, in the matrix of Figure 3, anti-aircraft weapons F
Target designation number a where 1 is the number of targets that can be assigned (shot)
, (generally an integer greater than or equal to zero) are entered, and the number of firearm assignments, which is the number of anti-aircraft weapons assigned to the target T1 corresponding to the column, is entered (generally an integer greater than or equal to zero). Therefore,
Figure 3 shows each anti-aircraft weapon/target combination (I, J)
This is a matrix display of the threat level CIJ corresponding to .

Here, the following explanation will be made on the assumption that when the sum of 81 is a, and the sum of b is b, then a x b. a, Focus on the row of anti-aircraft firearms Ff that is >0, select the highest threat level and the second highest threat level in that row, find the difference between them, set it as C1, and set this as ax ) 0 Execute for all anti-aircraft firearms F, (I = 1 to N) rows.

J*)C) combination is obtained.

A combination matrix (XIJ) with initial values of all 0 is created assuming a combination of a pre-selected anti-aircraft weapon and a target, and each time a combination (I*, J*) is obtained, the corresponding element is set to 1, and the calculation is performed. After all are completed, the combination matrix CXtx] is output. In addition, each time a combination (I*, J*) of anti-aircraft firearms and targets is obtained, the target designated number a of target anti-aircraft firearms, the assigned number of target anti-aircraft firearms,
and its numerical value decreases by 1, and at least one of these sums (a=Σa,, b=ΣbJ) is O
It will continue until it reaches vc.

Using the method described above, you can find the most threatening combination for each anti-aircraft weapon. Among these, by configuring a procedure in which the target designation number a1 and the firearm assignment number S are exchanged, it is possible to create a combination of firearms with the highest degree of threat for each target.

Next, FIGS. 4(a) to (e) and 5(a) to (C
), an example of the procedure described above will be explained. first,
From the anti-aircraft firearm information and the target information, as shown in Figure 4 (al), the initial threat level C8, the number of designated targets a, and the number of assigned anti-aircraft firearms are set.The sum a of the designated number of anti-aircraft weapons is 6
．． Since the sum of the number of anti-aircraft weapons assigned to the target is 7, we will discuss based on the small number of anti-aircraft weapons.

In FIG. 4 1b+, the threat degree CtJ of the anti-aircraft weapon Fl from the target is shown in the first row, with the maximum being 6 and the second largest being 3. This difference 01 is 3, and the same goes for C! =4, C1=2 Threat level C□ in this line
The maximum value of , is CZS. Therefore, the combination (I*, J*) of the anti-aircraft weapon and the target is (2I a), and the combination matrix (XIJ) shown in FIG. 4(C) is X,
Only 3 is considered 1.

Next, the target designation number a2 of the anti-aircraft firearm F corresponding to the combination of anti-aircraft firearms and targets shown in FIG. 4(d) - (2, 3)
= 3 is reduced by 1 to 2, and the number of anti-aircraft weapons assigned to target Ts b
Subtract 1 from 3=1 to get O. Here, the sum a of the target number of anti-aircraft firearms and the sum of the number of target anti-aircraft firearms assigned are both 0.
However, as shown in FIG. 4(e), the number b3 of anti-aircraft weapons assigned to the target T3 has become 0, so the threat level CtS of the column of the target l1ls is set to O.

In this state, the same procedure is repeated, and the situation is shown in a matrix display in FIGS. 5(a) to 5(C).

First, in Figure 5 (a), the combination of anti-aircraft weapons and targets (engine *,
J*) is (1, 1) and combination matrix [Xl,
] is added with X11=1. The sum a of the number of anti-aircraft firearms assigned to the target and the sum of the number of anti-aircraft firearms assigned to the target are both not 0, but the number b of anti-aircraft firearms assigned to the target Tl! has become 0, so the threat level 011 in the target TI column is set to 0. In the next step, the combination of anti-aircraft weapon and target (I*, J*) is (2,
4) x, 4=1 is added to the combination matrix (XIJ).

Figure 5 (bl) shows the combination of anti-aircraft weapons and targets.

J*) is (1,4) and combination matrix CXI
x14=1 is added to J). Both the sum a of the number of designated targets for anti-aircraft firearms and the sum of the number of assigned anti-aircraft firearms for the target are not O, but the number of designated targets al for anti-aircraft firearms Fl is 0, and the number b4 of assigned anti-aircraft firearms for target T4 is 0. Therefore, the threat level C of the row of anti-aircraft weapon Fl and the column of target T4 is set to 014. The next step is to combine anti-aircraft weapons and targets (I*
, J*) is (2,2) and the combination matrix (XI
x, , = 1 is added to J ). Although the sum a of the number of designated targets for anti-aircraft firearms and the sum of the number of assigned targets for anti-aircraft firearms are both not 0, the number of designated targets for anti-aircraft firearm F2, a, is O, so the threat of anti-aircraft firearm F The degree CIJ is assumed to be O.

Figure 5 (C) shows the combination of anti-aircraft weapons and targets (I*, J*
) becomes (3, 2), and the combination matrix (XIJ)I
cx3. = 1 has been added, and the sum of the designated target numbers of anti-aircraft weapons has become 0, so output the combination matrix (XIJ) to achieve the objective.
