Description
Technical Field
The invention relates to a simulated ammunition flight path measuring system and a non-visual confrontation training method.
Background
At present, the soldier confrontation training develops towards the direction of intellectualization, a direct aiming weapon usually replaces ammunition with laser to carry out the soldier confrontation training, and the specific method is to additionally install a laser transmitter on the weapon and install a laser decoding device on personnel and equipment; when the weapon emits the coded laser beam during the training, the laser decoding device installed on the personnel and the equipment judges that the weapon is hit if the coded laser beam is received.
However, the use of the above-mentioned soldier confrontation training system has the following major drawbacks in confrontation training: the ammunition launched by the solid weapon has strong penetrability, particularly armor piercing bombs and some special ammunitions, and can penetrate armor and walls. In special combat, a soldier can find a person on the other side of the wall through the thermal imaging camera and strike a target by launching a armor-piercing projectile. In the confrontation training of the real soldiers, due to the inherent characteristic of laser, the laser transmitter and the paper additionally arranged on the weapon cannot penetrate, so that the confrontation training under the condition of non-visibility cannot be realized, and the confrontation training of the real soldiers, particularly the effect of special combat, is seriously influenced.
In a patent 'CN 113593333A applied to a building simulator of an actual combat system', a laser receiver array is arranged on an outer wall of a building, and after a simulated laser cannonball hits the laser receiver, the damage effect of the cannonball after penetrating through the wall is calculated according to the space coordinate position of the hit laser detector. The scheme has the following defects: the laser receiver array is arranged on the wall body, gaps with certain sizes exist among the laser receivers, when a certain laser detector is hit, only the extension line of the connecting line between the laser detector and the weapon can be used as the trajectory of a projectile penetrating through the wall body, and when personnel behind the wall is not on the extension line and is in the gaps among the laser detectors, the personnel behind the wall cannot be hit. That is to say, due to the insufficient measurement precision and resolution of the flight path of the simulated ammunition, the method of simply laying the laser receiver array cannot completely meet the requirement of special combat on the confrontation training of non-visual targets.
