多管齐射武器弹幕参数的细分光幕阵列测试方法

针对准确测试多管齐射武器弹幕参数,提出了一种细分六光幕阵列测试方法。研究的细分光幕阵列将探测空间划分为多个子探测平面区域,通过采集多管齐射武器发射的多发弹丸穿过每个光幕时输出的信号并计算时刻信息,依据穿过对称光幕的时间间隔相等的原理,利用穿过同一光幕不同位置的时间差可从众多时间序列中识别出每发弹丸穿过6个光幕的时间序列组合,从而计算出每发弹丸相应的飞行参数。研究的算法经仿真验证,结果表明算法有效。此外还给出了光幕的实现方案,并对高射频连发射击试验进行了验证。

Divided screen array measurement method of projectile-curtain parameter for multibarrel volleyed weapons

In order to meet the demand of measuring the projectile-curtain parameter of multibarrel volleyed weapons, a method basing on the divided six-light-screen array was put forward. When projectiles from multibarrel volleyed weapons past through the divided screens, each small screen sensor would put out signals. The multi-channels data acquisition device captured these signals and then calculated the times of between different signals. The time sequence for a projectile past through six screens can be identified according to the principle that the flying time between the symmetry screens was the same and the flying time in different position in one screen was different. Finally the flying parameters for every projectile can be worked out. The efficiency of the algorithm has been verified by emulation tests. Besides, the implementation scheme for the light screen was given, and has been verified by the high rate firing tests.
