摘　　要：在舰炮弹道修正中,由实测的一段弹道参数推算落点必须用到弹丸速度。地面火炮雷达测速模型不适用于舰炮,针对舰炮发射弹道修正弹后舰艇运动和摇摆的特点,提出了考虑舰艇运动的两种舰炮弹道修正弹速度模型。模型一利用跟踪雷达测量的相对坐标、测量坐标的时间间隔以及舰艇航速、航向计算修正弹速度;模型二利用跟踪雷达测量的径向速度计算修正弹速度。通过仿真得出了两模型的特点和不同使用时机。研究结论为进一步研究雷达测量弹道参数在推算落点中的应用提供参考。To forecast fall point of trajectory correction projectile with measured trajectory parameters need the projectile velocity. In order to resolve the problem that calculating velocity was influenced by warship maneuver after trajectory correction projectile was fired, two models of calculating velocity were presented. The first model made use of relative trajectory coordinates measured with radar, measuring time interval, and warship velocity, course, and sway angles. The second model made use of relative radial velocity. The characteristics and using occasion of two models were achieved by simulating. The research conclusion was reference for trajectory parameters measured by radar to be used to forecast fall point.
