制导工具误差对导弹射击精度的影响分析

Analysis on Effect of a Missile's Guidance Instrument Error on Fire Accuracy

探讨了影响导弹射击精度的主要工具误差系数偏差，建立了导弹惯测组合输出仿真和误差补偿仿真的数学模型。在标准弹道基础上将建立的仿真模型加入导航计算过程，建立了惯测组合工具误差的干扰弹道模型，并计算分析了不同射向、射程下的工具误差系数偏差对导弹落点的影响，为进一步研究减小制导工具误差的途径打下了基础。

In this paper, the coefficients deviation of major instrument errors which influence the missile's fire accuracy are inquired in theory, the simulated mathematical models of error compensation and IMU output are established and studied. Moreover, the navigation computing is added up to the established simulated model on basis of the standard trajectory, so the model of interference trajectory of IMU error is established, and the routines are programmed. The effects of instrument error coefficient deviation of the different direction and range on the impact point are also computed and analyzed, which provides the basis of further study of the means of decreasing the guidance instrument error.
