摘  要:采用惯性导航系统的舰舰导弹作为海战场最重要的攻击武器,能否快速准确地在舰艇上对导弹捷联惯性导航系统进行初始对准,是影响舰舰导弹捕捉概率的重要因素。动基座对准误差导弹捷联惯性导航系统作为的初始误差,会随着工作时间增长不断累加,导致末制导雷达开机时导弹散布误差和航向误差角不断增大,将致使末制导雷达的捕捉概率下降。基于动基座初始对准误差对导弹飞行控制误差的影响,以目标位置误差圆分布为基础,建立舰舰导弹捕捉概率计算模型,通过不同条件的参数设置,仿真计算出某型舰舰导弹动基座初始对准误差对目标捕捉概率的影响。结果表明捕捉概率近似线性下降,下降值约为静基座对准时的4.2%~6.5%.The shipborne ship-to-ship missile with INS is an important attacking weapon in naval battle. Therefore,the rapid and accurate initial alignment of ship' s INS (SINS) on moving ship becomes one of the critical technologies for the shipborne anti-ship missiles. As the initial error of SINS, the alignment error is accumulating over time, which can make the missile dispersion and yaw error angles increase, resulting in the decrease in the acquisition probability of homing radar. Considering the effect of initial alignment error on auto-control terminal error, a calculation model of acquisition probability for ship-to- ship missile is established based on the model of target position error. The influence of initial error of a certain ship-to-ship missile on target acquisition probability is analyzed by setting the different conditions and parameters. The results show that the probability is decreased linearly with 4. 2% - 6. 5% of static alignment.
