2. Description of the Related Art A conventional small arms fire evaluation system is shown in FIG.
As shown in the figure, a shooter sensor 16 placed near the shooter and a T-bar unit 4 placed near the target 2,
It is composed of an analysis / display unit 18 connecting these. First, the shooter sensor 16 detects a shock wave caused by a bullet fired from the shooting gun 14, and then the T-bar unit 4 detects the shock wave due to the arrival of the bullet. At this time, the T-bar unit 4 includes four shock wave sensors 9 to 12.
Is installed, and from the time difference between the shock waves reaching these sensors 9 to 12, the analysis / display unit 18
The target impact position of the bullet is analyzed and displayed.

However, in the above-described evaluation system, there is a case where a bullet from another adjacent shooter cannot be distinguished from a self-propelled bullet. This is because the self-bomb is distinguished from the other ammunition based on the time required from when the shooter sensor 16 detects the shock wave to when the T-bar unit 4 detects the shock wave. In other words, if the T-bar unit 4 operates within a certain period of time after the operation of the shooter sensor 16, it is determined that the T-bar unit 4 is caused by the own bullet. For this reason,
If, within this fixed time, the own bullet and the other bullet are T
When flying to the bar unit 4, the discrimination between the two becomes completely impossible.

The present invention has been made in order to solve such a problem, and even if the shots of other shooters and the shots of the self-shot bullet are substantially simultaneous, small-armed firearms capable of discriminating between themselves and others can be distinguished. An object of the present invention is to provide a shooting hand discrimination method in an evaluation system.

FIG. 1 shows an embodiment of a small arms shooting evaluation system according to the present invention. In this system, first, when a shooter fires a bullet from a gun 14, there is a shooter sensor 16 that detects a shock wave of the bullet, and an analysis / display unit 18 that stores the detection time of the shock wave. Next, a T-bar unit 4 for measuring the passing position of the fired bullet is installed near the target 2 which is the target of shooting. The T-bar unit 4 is provided with four shock wave sensors 9 to 12, which measure the speed of the bullet with the sensors 10 and 12, and determine the passage position of the bullet from the shock wave arrival time difference between the sensors by the sensors 9 to 11. Is measured. Also, shooter gun 1
4, a muzzle direction sensor 20 is attached,
The analysis / display unit 18 includes a circuit for detecting the muzzle direction (l / sonic speed) seconds before the time at which the shooter sensor 16 detects the shock wave. Here, 1 is the distance between the muzzle of the gun 14 and the shooter sensor 16, and the muzzle orientation at the moment when the bullet is fired from the gun 14 is obtained.

Next, in this shooting evaluation system,
When the impact is detected in the measurement area of the T-bar unit 4 near the target 2 within a certain time after the shooter sensor 16 detects the shock wave, the discrimination as to whether or not this is due to the own bullet is performed.
The analysis / display unit 18 performs the comparison with the muzzle direction. For example, when two shots are detected in the measurement area of the T-bar unit 4 within a predetermined time after the shooting sensor 16 detects, (l / sonic speed) at the time when the shooting sensor 16 of the player detects the impact. The impact position estimated from the muzzle direction two seconds ago is compared with the two impact positions, and only the own impact position is selected and displayed on the analysis / display unit 18.
