FIG. 2 is a diagram showing display contents displayed on the display 18 during a series of operations from searching for a target to aiming and shooting. The display image 19 includes a target image shown in the infrared image 3. 20, a sighting point reticle 21, a first aiming reticle 22, and a second aiming reticle 23 are displayed.

In the aiming device for small arms constructed as described above, the target is searched by viewing the display image 19 as shown in FIG. 2A, and the target is found as shown in FIG. 2B. The target 20 is superimposed on the aiming point reticle 21. Here, the aiming point reticle 21 is made to coincide with the measurement direction of the distance measuring device 4 by the aiming point reticle superposition position calculating means 12. Since the relationship between the muzzle direction of the small arms 1, the imaging direction of the infrared camera 2, and the measurement direction of the distance measurement device 4 is known, for example, if the aiming direction 7 is set to be the measurement direction of the distance measurement device 4, The muzzle direction 1 and the imaging direction of the infrared camera 2 are also known. In this state, when the distance to the target 20 is measured by the distance measuring device 4 and the aiming direction is measured by the aiming goniometer 6, the trajectory calculating means 10 measures the distance measurement result 5 to the target 20 and the distance. Aiming direction 7 is input. further,
The trajectory of the bullet fired from the small arms 1 can be calculated by the trajectory calculation means 10 by inputting the temperature, wind direction, wind speed and the like obtained by another means through the trajectory calculation specification input device 8.

The trajectory calculation means 10 includes a method using a shooting table, a method for solving a differential equation of trajectory, and the like. Methods for solving ballistic differential equations include mass models, modified mass models,
There are six-degree-of-freedom models and the like. Whether to select a method using a shooting table or a method for solving a differential equation depends on the ability of a computer for calculating the trajectory and the required accuracy of the trajectory. Here, as a specific example, one example of a method using a projection table will be described.

FIG. 3 shows an example of a projection table. In FIG.
The firing distance is the distance to the target, the high angle is the vertical angle at which the small weapon is aimed, the bullet flight time is the time from when the bullet leaves the muzzle to reach the target, the drift angle is the angle at which the bullet shifts horizontally, In each case, the initial speed of the bullet, the temperature, the air pressure, the wind direction and the wind speed are the values at the time of the standard state. The high angle correction amount is the correction amount of the high angle when the initial speed, temperature, atmospheric pressure, and headwind deviate from the standard state, and the bullet flight time correction amount is also the bullet flight time when the initial speed, temperature, pressure, and headwind deviate from the standard state Indicates the amount of correction. The correction by the crosswind indicates the amount of displacement of the bullet in the horizontal direction due to the crosswind. The shooting table is configured by giving a plurality of tables similar to those in FIG. 3 according to the vertical angle when the target is viewed from the small arms. In FIG. 3, E1 to E19, T1 to T19, D1
D19, ΔEv1 to ΔEv19, ΔEt1 to ΔEt1
9, ΔEp1 to ΔEp19, ΔEw1 to Ew19, ΔT
v1 to ΔTv19, ΔTt1 to ΔTt19, ΔTp1
ΔTp19, ΔTw1 to ΔTw19, ΔLw1 to ΔLw
19 is a unique value depending on the type of the bullet, and is given as a numerical value.

FIG. 3 is a projection in the case where the vertical angle when the target is viewed from the small arms is 0 degree, that is, when the target is present in the horizontal direction, and the aiming direction 7 measured by the aiming goniometer 6 is horizontal. Suppose the direction was indicated. At this time, assuming that the result of measuring the distance to the target 20 by the distance measuring device 4 is 500 m, the high angle of the standard condition is E9 degrees, and the bullet flight time is T9.
Second, the drift angle is D9 degrees. Therefore, initial speed, temperature,
When the atmospheric pressure and headwind are in the standard state and there is no crosswind, the muzzle direction of the small arms is changed from the direction of the target 20 to the vertical direction by E9.
If the bullet is directed in a direction at an angle of D9 degrees in the horizontal direction, the bullet reaches the target 20 T9 seconds after leaving the muzzle. Next, the deviation from the standard state of the initial speed is Δvm / s, the deviation of the temperature from the standard state is Δt ° C., the deviation of the atmospheric pressure from the standard state is ΔphPa, and the deviation of the head wind from the standard state is Δwm /.
s and the crosswind is Lwm / s, the high angle correction amount Δ
E is represented by Equation 1, the bullet flight time correction amount ΔT is represented by Equation 2, and the correction amount ΔD due to crosswind is represented by Equation 3.

[0016]

(Equation 1)

[0017]

(Equation 2)

[0018]

(Equation 3)

In this case, the high angle is corrected by equation (1), and becomes equation (4). Similarly, the bullet flight time is corrected by Expression 2 and Expression 5, and the horizontal angle becomes Expression 6 by correcting the drift angle by the cross wind. Therefore, if the muzzle direction of the small arms is directed in a direction at an angle of E degrees in the vertical direction and D degrees in the horizontal direction from the direction of the target 20, the bullet will not reach the target 2 in T seconds after leaving the muzzle.
Reach 0.

[0020]

(Equation 4)

[0021]

(Equation 5)

[0022]

(Equation 6)

In the above example, the case where the target viewed from the small firearm is in the horizontal direction at a shooting distance of 500 m has been described. However, the measurement result of the firing distance and the vertical angle of the target viewed from the small firearm have a value not in the shooting table. In this case, a necessary value may be derived from the projection table by interpolation and calculated by the same method as described above.

When the trajectory is calculated, the direction in which the muzzle of the small arms 1 for firing the bullet is directed and the flight time from when the bullet leaves the muzzle to when the bullet reaches the target 20 are calculated, and are output from the trajectory calculation means 10.

2 indicates the direction in which the muzzle of the small arms 1 is directed, and the second aiming reticle 23 indicates the direction in which the muzzle of the small arms 1 is currently facing.

The inclinometer measures the elevation angle based on a horizontal plane, and the azimuth sensor measures the azimuth angle based on a magnetic north reference. Will point. Therefore, after measuring the distance, the aiming point reticle 21 and the first aiming reticle 22 indicate points fixed in space, so that they are fixed on the infrared image 3 unless the target 20 is moving. Aim point reticle 2 even if small arms 1 move
The relative positional relationship between the target 1, the aiming reticle 22, and the target 20 on the display image 19 does not change. On the other hand, since the second aiming reticle 23 indicates the direction in which the muzzle is facing, the second aiming reticle 23 is fixed on the screen displaying the display image 19 of the display 18, and when the small arms 1 is moved, the infrared image 3 is displayed. Move.

Next, as shown in FIG. 2D, by aligning the first aiming reticle 22 and the second aiming reticle 23, the muzzle of the small arms 1 is aimed at the bullet to hit the target 20. Can be pointed exactly in the direction. Since the bullet reaches the point indicated by the aiming point reticle 21, if the shooting is performed in this state, the bullet hits the target 20.

For example, when the aiming point reticle moving signal 25 is output from the aiming point reticle moving means 24, the aiming point reticle 21 is displayed on the display 18 on the display 18 regardless of the movement of the small arms 1. It is fixed on the screen so that it can be moved in the space by moving the small arms 1. Then, the aiming point reticle movement signal 25
Is lost, the aiming point reticle 21 is fixed in space. At this time, aim point reticle position 1 which is a position in space
3 is input to the first aiming reticle superposition position calculating means 14 so that the relative positional relationship between the first aiming reticle 22 and the aiming point reticle 21 does not change.
