导弹高精度快速水平对准算法

为提高弹道导弹射击精度,考虑水平对准误差对射击精度的影响,提出了一种适于晃动环境的水平对准算法,给出了数学模型。仿真结果表明：该算法对准精度高,在90 s内对幅值不大于50′的随机晃动水平失准角的估计误差小于1′,优于原水平对准算法,且计算量小、易于实现。

Algorithm for High Precision Horizontal Alignment of Ballistic Missile

To improve the shooting accuracy of the ballistic missile, a horizontal alignment algorithm that was suitable for the shake environment was put forward when the horizontal alignment error on precision of fire was considered in this paper. The computation model was given out. The simulation results showed that the horizontal alignment precision of the algorithm was high, which estimation error of angular misalignment was less than 1＇ under conditions that the swing was not more than 50＇ in 90 seconds, so it was better than the original alignment and was easy to be realized because of its little computation.
