Abstract

PURPOSE:To minimize variations in the condition of combining firearms and targets displayed on a display device, and to improve the efficiency of assigning the firearms, by preferentially selecting the preceding combination when the extent of variations in the position and velocity of the targets selected by the combination made at the preceding time is small. CONSTITUTION:A criticality calculating circuit 1 calculates the criticality Cij of each of targets Tj to each of firearms Fi, based on the target data and the firearm data. A criticality comparing circuit 2 calculates a difference between the criticality Ci0j0 corresponding to a firearm i0 and a target j0, which show X'ij>=1 among the firearm-target combination solutions X'ij outputted from said comparing circuit 2 at the preceding time, and the criticality Ci0j of other targets Tj on the firearm i0 line, and stores the calculated difference into a memory. Judging circuits 3 and 5 judge the presence of a target j over a threshold value K. In the case where there is no target j over the threshold value K, a correcting circuit 4 substitutes the firearm-target combination solution X'i0j0 made at the preceding time for the firearm-target combination solution Xi0j0 obtained this time, and thus the criticality Ci0j0 into zero, thereupon a criticality matrix, the number of designated targets and the number of assigned firearms are stored in the memory. A firearm-target combining circuit 6 decides on the combination of firearms and targets in the case where the criticality Cij shows other figures than zero.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a firearm assignment device, and in particular, a firearm assignment device characterized by smoothing and efficiently determining combinations of firearms and targets in a command information processing system. [Conventional technology] Conventionally, this combination of firearms and targets is determined by calculating the threat level of each target against each firearm from the current position, speed, etc. of the target and the position of the firearm at a certain period. Firearms and targets were all combined to maximize the sum of threat levels. Regarding this, for example, anti-aircraft weapon allocation device 1: Japanese patent application No. 61-233
653, Firearms Assignment [: Patent Application 1986-283693
FIG. 2 is an explanatory diagram showing the relationship between the number of designated targets, the number of assigned firearms, and the threat matrix.

However, the number of designated targets refers to the number of targets to which firearms can be assigned (fired), and the number of assigned firearms refers to the number of firearms to which targets are assigned.

Figure 2 shows the relationship between the number of target designations ai, the number of firearms assigned bj, and the threat level (ma) + Jx Cij. , the number of firearms assigned to each target bj (j=1,..., m)
9. The threat level Cij between the firearm Fi and the target 11 is expressed in a matrix, and this is called the threat level matrix. This is an explanatory diagram showing the conventional technology, for example, an anti-aircraft weapon allocation device: Japanese Patent Application 1986.
-233653, the contents are shown in Figure 05g4, which calculates the combination of firearm and target. FIG. 4 is an explanatory diagram showing a procedure for determining a combination of a firearm and a target in the case of FIG. 3; The details of the combination will be explained below with reference to Fig. 3.4.

Threat matrix Cij (+ ==1 e 2 ; J
= 1 + 2), as shown in Figure 3, looking at the processed data this time, the second thickest maximum value ri9 in the first row is 8, and the CI as the difference between the two is C,
:9-8=1 and fx,b Similarly, for J<2 rows, C,=8-8=O.

Therefore, in general, for the i-th row, the maximum value Fic of ci (L==L* 2) is 1, and the threat level of this row is j (j
=1.2), the maximum value is CI□=9. Therefore, the combination of firearm and target (1, J) F'i (1, 2) is obtained and Xl! only 1.

Next, from al = l, set a 1 = 0, and b2 =
Subtract 1 from 1, making it = 0. Here, both the sum a of the target designated number of firearms and the sum bri of the target assigned number of firearms are not 0, but since the target designated number of firearm 1 is O and the target number of firearms assigned is O, Cij = O(j=X, 2
) and Ci,=Q(supervisor=1,2). If the same procedure is repeated below, the next target and firearm combination (l eJ) is (2,1).
is selected and ends.

As a result, as shown in the currently processed data in FIG. 3, when the position and speed of the target change slightly, the combination of firearm and target changes.

[Problem to be solved by the invention]

In the conventional firearm allocation system described above, the combination result of the firearm and target calculated at a certain period changes each time due to subtle changes in the target position and speed, and the result of the combination of the firearm and target displayed on the display device is The disadvantage is that the combination situation changes frequently, making it difficult for the operator to make appropriate judgments.

The object of the present invention is to eliminate the above-mentioned drawbacks and to avoid the position of the target selected in the previous combination, as long as no target appears whose resistance to the firearm suddenly increases.

To provide a firearm assignment device which performs efficient combinations by preferentially selecting targets that have been retreated in previous combinations when the amount of change in speed is small.

[Failure to solve the problem]

Substitute o and set the threat level Ciojo to 0, and from the target designation aaio of firearm io and the number of firearms assigned to target jo bjo, the current combination solution of firearm and target, >(ioj
If the target specified number aio becomes 0 by subtracting o, all C1oJ (j=1..1m) in the io row will be set to O, and bjo will be 0.
Then, all Cij in the jo column.

(""to...,n) is set to 0, and a correction circuit stores the threat level matrix, the number of designated targets, and the number of firearms assigned in the memory; and the determination result of the determination circuit (1) determines that Ci oj is equal to or higher than the threshold value. If there is no eye jaj, then X′ij≧1 among the previously output firearm and target combinations mX′ij, through the processing by the correction circuit, and if there is, without the processing by the correction circuit. It is determined whether or not the processing by the threat level comparison circuit has been performed for all combinations of firearms and targets, and if there are combinations of firearms and targets that have not been processed, the process returns to the threat level comparison circuit. a determination circuit (2) for determining the combination of a firearm and a target for those whose threat level Cij is other than 0 based on the threat level matrix outputted from the correction circuit, the number of designated targets, and the firearm assignment aK; and a memory for storing the output of the threat level comparison circuit and the correction circuit.
