摘　　要：水下弹丸速度的测量一般是测量弹丸的速度大小,而对弹丸的位置、飞行方向关注较少.本文设计了一种可以检测水下弹丸位置、飞行方向、速度大小的弹丸定位系统.该系统通过在弹丸预射轨迹附近布置多个压力传感器,采集弹丸通过传感器附近时的峰值压力以及峰值压力的发生时刻,通过公式可以对弹丸在传感器附近的位置信息、速度大小和飞行方向进行解算,从而实现对弹丸的多点定位.仿真结果表明,该系统可以通过压力传感器得到的峰值压力和峰值压力的发生时刻实现对弹丸的水下定位.The measurement of property of underwater projectile generally measures the speed of the projectile,paying hardly attention to the position and flight direction of the projectile.This work proposes a projectile positioning system which capable of detecting underwater projectile position,flight direction and speed.The system collects the peak pressure and the peak pressure occurrence time when the projectile passes near the sensor via arranging a plurality of pressure sensors in the vicinity of the projectile pre-shot trajectory.The position information,speed and flight direction of the projectile near the sensor can be calculated by the formula to realize multi-point positioning of the projectile.The simulation results show that the system can realize the underwater positioning of the projectile through the peak pressure and peak pressure occurrence time acquired by the pressure sensor.
