Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a display device for fire control, and more particularly, the present invention relates to a display device for fire control, and in particular, displays information such as the point of destruction of a target, the passing position of a target at the time of launch of a projectile fired from a firearm, and the firearm at that time. The present invention relates to a fire control display device for displaying a target position and a position of a target.

[Conventional technology]

When attempting to attack or threaten, as a last resort, these targets against an aircraft or ship that has violated its airspace or territorial waters, the commander designates the targets to be attacked for each friendly weapon and transfers this information to the weapons department. Command and communication is being carried out. This is called firearm allocation, and is done to prevent situations such as multiple weapons attacking the same target due to each firearm attacking on its own, and to ensure efficient firearm use. There is.

In general, when allocating firearms, a commander determines the combination of targets and firearms based on their relative positions while monitoring the target position from sensors such as radar displayed on a display device and the position of friendly firearms. This is done by instructing the department in charge of each firearm with the results. For example, information on the combination of a target and a firearm is processed in advance based on its type, performance, etc., and the result is displayed on a display device as shown in Figure 4. is displayed with a firearm assignment line. Firearms are assigned by reconfirming this with the commander.

The display at this time connects the target T and the firearm F with a firearm assignment line R, and shows the direction of movement of the target from the target T.

[Problem that the invention seeks to solve]

The problem to be solved by the present invention is that, as mentioned above, the firearm assignment line is sometimes displayed ignoring the direction of movement of the target, so it is difficult to accurately determine the firing direction and firing point of the projectile for each firearm. The problem is that it is difficult to judge and give instructions.

〔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 showing an overview of the operation of an embodiment of the invention, and Fig. 3 shows the operation of an embodiment of the invention. flowchart,
FIG. 4 is an explanatory diagram showing a self-answer display according to a conventional technique.

First, an overview of the present invention will be explained with reference to FIG. 2.

The present invention is based on the position of the target T obtained from a sensor such as a radar and the performance specifications of the firearm F, and a projectile capable of destroying the target T is launched at a predicted destruction point A on the maximum range E of the firearm F. The present invention provides a device that displays the firing direction G of a firearm (hereinafter referred to as the firearm firing direction) and the passing position C of a target T corresponding to the firing time. Regarding the present invention, the time at which the projectile is fired from the firearm F (hereinafter referred to as the firing time of the firearm)
The passing position C of the target corresponding to is shown on the predicted target course E, and when the target reaches the passing position C, if the projectile is fired in the firearm firing direction G, the maximum range H of the firearm and the predicted target course are This is the point where the target can be destroyed at the intersection with E, that is, the predicted destruction point A.

Next, the derivation of the predicted destruction point A and the target passing position C corresponding to the firing time of the firearm will be described in rectangular coordinates with the firearm F shown in FIG. 2 as the origin.

First, find the predicted defeat point A. Assuming that the target T is in uniform linear motion, the predicted course (x,
y) is the initial position of the target T (Xo.

yo) If the speed is (X□y)'0), it is expressed by equation (1).

(y yo) = (夛0/reasonable) (Xxo)...
(1) Also, the position (x, y) indicating the maximum firing range H is a circle.If the maximum firing range is RF, it can be expressed by equation (2).

x2+y" = R+ F2... (2) Here, by solving equations (1) and (2) as simultaneous equations, the position of the predicted destruction point A can be found. This solution is a real number is valid, and the number may be 0, 1, or 2. If there are 0 solutions, the target predicted course E is outside the maximum range H, so it cannot be attacked. When the target predicted course E and the maximum range H touch, the point of contact becomes the predicted destruction point A. When there are two solutions, the target predicted course E and the maximum range H intersect, so the initial target T The intersection closest to the position is the predicted destruction point A, and the intersection far from the initial position of the target T is the predicted escape point B), and the target is located between this point and the predicted destruction point A (preferably, safely). It is necessary to take this into account and attack at predicted destruction point A).

Next, in order to hit the target T at the predicted destruction point A, the target passing position C corresponding to the time at which the projectile is fired from the firearm F at the speed ■F at the same time as the predicted destruction point A is determined. In this case, assuming that the time for the target T to move from the target passing position C corresponding to the firing time to the predicted destruction point A is equal to the time for the projectile to move from the firearm F to the predicted destruction point A, If we calculate the distance AC between C and the predicted defeated black man, we get equation (3).

A C= (R, /VF) Rikan T- et al. (3
) Therefore, if the position of the predicted destruction point A is (X person ryh), then the position of the target passing position C corresponding to the launch time is (X
ctyc) can be obtained as in equation (4).

By the method described above, it is possible to obtain the predicted destruction point A and the target passing position [C] corresponding to the launch time.

Next, an embodiment of the present invention will be described with reference to FIGS. 1 and 2, focusing on its configuration and operation.

Referring to FIG. 1, one embodiment of the present invention includes a display section 1, a destruction point calculation section 2, and a firing point calculation section 3. Firearm information signal 100 including the maximum firing range and firing speed of the firearm specified in advance, and the target position and its advancing speed (including direction) obtained by radar sensor etc.
The target information signal 101 including the target information signal 101 is input to the destruction point calculation unit 2.

The destruction point calculation unit 2 calculates a predicted target course E from the position and advancing speed of the target T shown in the target information signal 101, calculates the intersection of the maximum range H shown in the firearm information signal 100, and calculates the predicted destruction point A. and the destruction point signal 10 indicating this

Further, a firearm information signal 100, a target information signal 101, an ejection point signal 102, and a firing point signal 103 are input to the display section 1, and the display section 1 displays a predicted target course E, a predicted ejection point A on the course, and a firearm F. The target passing position C, target T, firearm F, etc. corresponding to the firing time are shown, for example, as shown in FIG. 2.

Therefore, the display on the display unit is monitored, and when the display of the target T overlaps with the display of the target passing position C corresponding to the firing time of the firearm F, the firearm F is fired in the firing direction G. If so, the projectile will hit the target T at the predicted destruction point A.

Next, the operation of one embodiment of the present invention will be explained for each component block with reference to the flowchart of FIG. First, the target information signal 100 and the firearm information signal 101 are input (steps (2) and (2)).

The position of the target T (Xotyo
) and velocity ('o t Vo ) (step ■), and create, for example, equation (1) indicating the target predicted course (step ■). Also, from the firearm information signal 101, the position of the firearm F (generally the origin of coordinates) and the maximum range R
F (step ■), and create, for example, equation (2) indicating the maximum range (step ■). Here, the above (1
) and equation (2), and calculate the position of the predicted destruction point A (step 2).

Next, from the target information signal 100 to the speed of the target T (interchange
j) 'o) is separated again (Step ■), the distance F of the maximum firing range of the firearm F and the firing speed ■F are separated from the firearm information signal 101 (Step ■), and the position of the predicted destruction point A is determined. From the data, a passing position C of the target corresponding to the firing time of the firearm F as shown in equation (4) as shown in equation (4) is calculated (step [phase]). Further, a target information signal 100, a firearm information signal 101, and a destruction point signal 1 indicating a predicted destruction point A.

According to the firing time signal 103 indicating the firing time, at least the predicted target course E, the predicted destruction point A, the positions of the target T and the firearm F, the target passing position C corresponding to the firing time of the firearm F, etc. are displayed as shown in FIG. 2, for example. (Step 0).

As described above, when the display of the passing position C of the target corresponding to the firing time of the firearm F and the display of the target T overlap,
If the firearm F is fired in the firing direction G, it will hit the target T at the predicted destruction point A.

In addition, the operations of steps (1) to (2) in the flowchart correspond to the destruction point calculation section 2, the operations of steps (2) to [phase] correspond to the firing point calculation section 3, and the operations of step (2) correspond to the display section 1, respectively. Therefore, a computer system configured by connecting a data input/output interface, a display terminal, a program memory, a data memory, a computer unit, etc. with a data bus has the configuration of this embodiment (display section 1, destruction point calculation section 2).
- It may be applied to each firing point calculation unit 3), or it may be applied to the entire configuration of this embodiment at once.

It is also possible to perform the above-mentioned display for several targets at any time, or to track these targets and display the passing position of the target corresponding to a new target, predicted destruction point, or launch time (i.e., the point at which the target passed this position). It is also possible to deal with fluctuations in data by displaying information such as the point at which the firearm was fired.

Furthermore, instead of a straight target predicted course, it is also possible to make a curve by predicting it from past data, or by storing past data in the destruction point calculation section or firing point calculation section and extrapolating the trend of that data. It becomes possible to do so.

As explained above, it is possible to accurately grasp the firing direction and firing point of the firearm.
