制导工具误差对再入点运动参数的影响分析

Effect of Guidance Instrument Error on Reentry Point’s Parameters

基于惯性制导工具误差模型,推导出存在工具误差时的再入点运动参数模型。并以加速度表误差为例,通过仿真计算得到不同精度的加速度表对再入点运动参数的影响。由于再入点运动参数准确与否直接影响到导弹引爆的控制精度,本文的研究成果可为以后进一步研究提高导弹引爆的控制精度奠定基础。

Based on the inertial guidance instrument error model, the model of reentry point＇s parameters is established in this paper. Through the digital computation, the effects of different accuracy accelerometer errors on reentry point＇s parameters are given. Because the accuracy of missile control in the altitude mostly depends on the accuracy of reentry point＇s parameters, the achievements of this paper can provide the basis for further improving of missile＇s controlling accuracy.
