Description
Technical Field
The invention relates to a simulated ammunition flight trajectory measurement system and a non-visual countermeasure training method.
Background
At present, the actual combat training is developed towards the intelligent direction, and the direct aiming weapon is usually used for carrying out the actual combat training by replacing ammunition with laser, and the specific method is that a laser transmitter is additionally arranged on the weapon, and a laser decoding device is arranged on personnel and equipment; the weapon emits coded laser beams during the countermeasure training, and a laser decoding device installed on personnel and equipment is judged to be hit if the coded laser beams are received.
However, the use of the above-described real combat training system has the following significant drawbacks in combat training: ammunition launched by the packaging weapon has strong penetrability, particularly armor piercing ammunition and some special ammunition, and can penetrate armor and walls. In special combat and anti-terrorist combat, a warrior can find personnel on the other side of the wall through a thermal imager and strike a target by launching armor-piercing bullets. In the actual combat training, because of the inherent characteristics of laser, the laser transmitter and paper added on the weapon cannot penetrate, and thus the combat training under the non-universal condition cannot be realized, and the actual combat training, in particular the effect of special combat and anti-terrorism training, is seriously influenced.
In the patent CN113593333a, a building simulator applied to an actual combat system is proposed to arrange a laser receiver array on an outer wall of a building, and after a simulated laser projectile hits a laser receiver, the destructive effect of the projectile after passing through the wall is calculated by the spatial coordinate position of the hit laser detector. The scheme has the following defects: when a laser detector is hit, only an extension line of a connecting line between the laser detector and a weapon can be used as a trajectory of a projectile penetrating through the wall, and when a person behind the wall is not on the extension line and is in the gap between the laser detectors, the person behind the wall cannot be hit. That is, due to the insufficient measurement accuracy and resolution of the simulated ammunition flight trajectory, the countermeasure training requirements of special combat and anti-terrorism training on the non-vision target cannot be completely met by a method of simply arranging the laser receiver array.
