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5 m距离爆炸时,光波和声波到达的时间差为14.7 ms；传感器不同角度的试验距离为8 m～20 m.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.
