摘　　要：针对海上运动目标定位误差较大的特点,制导炮弹多发同时弹着法(MRSI)可有效提高命中精度和火力密度。初速可控舰炮具有发射弹丸初速可调的优势,发射的制导炮弹可以进行弹道修正并以预先规划的制导律攻击目标。通过建立炮弹外弹道模型和带落角约束的最优制导律,提出了海上目标提前点计算方法,根据制导炮弹弹道特性,在分析初速固定舰炮火控方法的基础上,研究了初速可控舰炮的火控解算方法,并进行了算例仿真。结果表明,初速可控舰炮可大幅增加同时弹着的弹丸数量,增强火力密度。To the characteristics of large error in sea target positioning the method of Multiple Rounds Simultaneous Impact(MRSI)of guided projectile can effectively improve the hitting accuracy and firepower density.The shipborne gun with controllable muzzle velocity can adjust the muzzle velocity of guided projectiles correct the trajectory of the projectile and attack the target by using the preplanned guidance law.The models of projectile exterior ballistic and the optimum guidance law with angle constraints are established and the method for calculating the predicted point of sea target is proposed.According to the guided projectile trajectory characteristics an analysis is made to the fire control method of the shipborne gun with fixed muzzle velocity based on which the fire control method of the shipborne gun with controllable muzzle velocity is studied.The simulation results show that the controllable muzzle velocity shipborne gun can greatly increase the number of simultaneous projectiles and enhance the firepower density.
