Position deviation measurement between projectile explosion and target for air defense system

舰炮武器系统精度试验常常需要分析炸目偏差,通过记录鞭炮爆炸时声光信号到达时间及输出幅度等,用声光方法验证可测量小当量炸药爆炸信号。在5m距离爆炸时,光波和声波到达的时间差为14.7ms;传感器不同角度的试验距离为8m～20m。通过爆炸声光信号的到达时间及试验距离检验,验证了用声光测量炸药爆炸信号可行。结合弹目偏差测量脱靶量数据,该方案可完成炸目偏差数据的统计分析。

Position deviation measurement between projectile explosion and target is important for accuracy test of naval gun system.By recording the arrival time and output amplitude of acoustic-optic signal during firecracker explosion,the concept of detecting the explosion signal of small equivalent gun powder based on acoustic-optic method was verified.The arrival time difference of acoustic wave and light wave was 14.7 ms at an explosion distance of 5 m.The receiving distance of the sensor was 8 m～20 m at different angles.The arrival time of the explosion acoustic-optic signal and the receiving distance of the sensor were tested.The results validated the feasibility of making the measurement using acoustic-optic signal.Combined with the distance error data between projectile and target,the statistical analysis of the deviation data could be done.
