Abstract: 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.
