摘要
立靶密集度是火炮武器的关键性能之一,是反映火炮射击精度的关键参数.火炮立靶密集度测量方法有木板靶法、声学靶法、光电靶法和照相法等.采用木板靶法,在炮口前方特定距离竖立一面木板靶,火炮射击时,弹丸穿越该靶面,用长度尺测量弹孔坐标,然后计算密集度.采用声学靶法和光电靶法,在炮口前方特定距离布置声学传感器或光电传感器,火炮射击时,传感器感知弹丸穿越该靶面的信息,由计算机自动给出弹丸坐标,然后计算密集度.木板靶法简单、直观,但测量误差较大;而声学靶法和光电靶法自动化程度高,但可靠性还有待于完善.照相法是目前技术条件下较实用的测量方法,而光电靶法是发展方向.
The vertical target dispersion of gun is one of the key parameters for gun weapon, which reflecting the firing precision of gun. The measurement methods include the wood plate target, the acoustics target, the photoelectrical target and the photograph. For the wood plate target, a vertical target stands at the muzzle ahead in a distance. When firing, the projectile passes through the vertical target, the coordinates of projectile holes are measured by ruler, and the dispersion is calculated. For the acoustics target and photoelectrical target, the acoustics sensors or CCI） sensors are arranged at muzzle ahead in a distance. When firing, the information of the projectiles passing through the target is acquired by the sensors, and the projectile coordinates are given by a computer automatically. The method of the wood plate target is simple and direct, but the measurement error is big. The methods of the acoustics target and the photoelectrical target possess high automatization, but the reliability needs perfecting. At present, the photograph method is a more practical method for measuring vertical target dispersion of gun. The method of photoelectrical target is a progress direction.
