Based on the information signal 341, the effectiveness calculating section 31 of the firearm allocating device 36 determines the effectiveness of firearm fire on the target for each combination of all targets and firearms, and determines the target / firearm combination based on the result. The unit 32 comprehensively determines the effectiveness and determines a combination of a firearm and a target. The result is monitored by a display system 35 and transmitted to a firearm system 34.
従来、この種の目標・火器組合せ判定は、最終的な目

目標と火器の組合せをまず決定する。以下決定された目
標と火器の組合せに対する有効度を０とし、同様の手順
をくり返すことにより残りの組合せを順次決定してい
く。なお、この際有効度０の目標と火器は組合さない。
ここで、第５図に示すようにb1〜b3で示すそれぞれの火

があっても１台の火器のみを組合せるようにしている。Conventionally, this type of target / firearm combination determination is performed by determining a combination that maximizes the total effectiveness of each combination in the final target / firearm combination result. For example, Japanese Patent Application No. 61-
There is the following method disclosed in 233653. That is, as shown in FIG. 4, the validity of the maximum validity M in each row of the validity matrix for all combinations of the target and the firearm calculated by the validity calculation unit 31 and the validity M of the second largest validity M The difference ΔM is calculated. Then, △ M in each of these rows
First, the combination of the target and the firearm corresponding to the maximum effectiveness M in the row having the maximum value is determined. Thereafter, the effectiveness for the determined combination of target and firearm is set to 0, and the same procedure is repeated to determine the remaining combinations sequentially. At this time, the target with the effectiveness of 0 and the firearm are not combined.
Here, as shown in FIG. 5, for each of the firearms indicated by b1 to b3, a combination with a plurality of targets that can be fired simultaneously by the firearm is possible, but each of the firearms indicated by a1 to a3 is possible. For a target, only one firearm is combined even if there is a margin in the target number that can be combined with firearms.
上述のように、従来の目標・火器組合せ判断手段は、
火器が組合せ可能な目標数に余裕があっても１つの目標
には１台の火器のみを組合せていた。目標に対する火器
の撃墜率を考えると、撃墜率が100％もしくはそれに近
い高い値の場合には１つの目標に１台の火器を組合せた
だけでも目標の撃墜が十分に期待できるが、この撃墜率
は一般的にはさほど高い値ではなく、撃墜率が低い場合
には１つの目標に１台の火器を組合せただけでは十分な
目標の撃墜が期待できない。このように、目標に対する
火器の撃墜率を考慮した場合、従来の目標・火器組合せ
判断手段では、火器が組合せ可能な目標数すなわち火器
が射撃可能な目標数に余裕があるにもかかわらず十分な
目標の撃墜が期待できないという欠点がある。As described above, the conventional target / firearm combination determination means is:
Even if there is a margin for the number of target firearms that can be combined, only one firearm is combined for one target. Considering the rate of firearms falling down against the target, if the shootingdown rate is 100% or a high value close to it, it is possible to expect that the target can be shot down by combining only one weapon with one target. Is not so high in general, and when the shooting down rate is low, it is not possible to expect enough shooting down of a single target with only one weapon. As described above, when the shooting-down rate of the firearms with respect to the target is considered, the conventional target / firearm combination determination means has a sufficient number of targets that can be combined with firearms, that is, the target number that can be fired by the firearms. There is a disadvantage that the target cannot be shot down.

ある。The target / firearm combination determination unit 1 receives the target information including the position and velocity of the target and the validity matrix signal 101 for all combinations of the target and the firearm obtained from the firearm information including the position and the range of the firearm, and As shown in FIG. 4, the maximum validity M and the second largest validity M in each row of the validity matrix and the validity difference ΔM are calculated. △ in each of these lines
First, the combination of the target and the firearm corresponding to the maximum effectiveness M in the row having the largest value among M is determined. Hereinafter, the validity for the determined combination of the target and the firearm is set to 0, and the same procedure is repeated to determine the remaining combinations sequentially and output the target / firearm combination signal 102. At this time, the target with the effectiveness of 0 and the firearm are not combined. Here, as shown in FIG. 5, one firearm can be combined with a plurality of targets that can be fired simultaneously, but one target has a margin in the number of targets that can be combined with firearms. Even if only one firearm is combined. The operation of the target / firearm combination determination section 1 described above is the same as the operation of the conventional target / firearm combination determination means.
撃墜率判定部２は、目標・火器組合せ判定部１から出

結果信号103を出力する。The down-rate determination unit 2 receives the target-firearm combination signal 102 output from the target-firearm combination determination unit 1, and obtains a target downrate K for each target-firearm combination by the following equation (1). K = K 1 = f (R) (1) Here, K 1 is a shooting down rate in the combination, and f
(R) is a function inversely proportional to the distance R between the target and the firearm.
Next, the down rate K is determined by the following equation (2), and a down rate determination result signal 103 is output.
ここでKAは設定変更可能な撃墜率の定数とする。 Here, K A is a constant of the shooting rate that can be changed.

る。The validity matrix updating unit 3 receives the validity matrix signal 101 and the down rate judgment result signal 103 and updates the validity matrix as shown in FIG. That is, if the determination result by the formula (2) indicates that the combination is determined, it is determined that there is no need to combine firearms for the target of the combination to further increase the shooting-down rate, and the validity of the column for the target in the validity matrix Are all 0. On the other hand, if the determination result is undetermined, it is determined that it is necessary to further combine firearms in order to increase the shot-down rate. Is kept as it is. The updated validity matrix is input to the target / firearm combination determination unit 1 as an updated validity matrix signal 104.

式により算出する。In the target / firearm combination determination unit 1 to which the updated effectiveness matrix signal 104 is input, the target / firearm combination determination is performed based on the updated effectiveness matrix, and the target / firearm combination signal 10
2 is output. Goals based on the updated effectiveness matrix
The down rate judging unit 2 to which the firearm combination signal 102 is input calculates a downtime rate obtained by integrating the currently input target / arms combination and the previous target / arms combination downtime. The down rate K for a certain target that combines this time and the previous time is as follows (3)
It is calculated by the formula.

べての火器組合せ可能な目標がなくなるまで実施する。 Here, Ki is the shooting-down rate between the firearm and the target combined in the i-th target / firearm combination determination. For example, assuming that the first shot down rate is K 1 and the second shot down rate is K 2 , the shot down rate K for the first and second shots is K = 1− (1−K 1 ) (1−K 2 ). Become. That is, the probability of not being shot down the first time is (1-
K 1 ), the probability of not being shot down the first or second time is (1-
Since K 1 ) (1−K 2 ), the probability of being shot down in either the first time or the second time is 1− (1−K 1 ) (1−K 2 ). Here, if i = 1, it becomes the same as the expression (1). As described above, the total shooting-down rate K calculated by the target / firearm combination determination up to the i-th time is determined by equation (2), and the same operation is repeated. This repetition is performed until the shooting-down rates of all the targets become K ≧ K A and the combination is determined, or until there are no more targets in which all the weapons can be combined.
以上説明したように本発明は、目標と火器を組合せた

撃墜率が設定したある値以上になるまで目標と火器を組
合せることにより、目標の撃墜率を著しく高め、撃墜の
期待値を大幅に向上できるという効果がある。As described above, according to the present invention, when the shooting down rate of a target when a target and a firearm are combined is equal to or less than a set value, the shooting rate is reduced as long as the target number that can be combined with the firearms (fireable) is sufficient. By combining the target and the firearm until the value reaches a certain value or more, there is an effect that the target shooting down rate is significantly increased, and the expected shooting down value can be greatly improved.
