地形匹配修正陀螺仪误差漂移系数研究

探讨了巡航导弹在巡航直飞段陀螺仪漂移误差对导弹视加速度的影响,结合地形匹配中的巡航弹航向角偏差研究,对依靠地形匹配分离陀螺仪误差系数方案进行了可行性分析,并且利用地形匹配数据对陀螺仪误差系数进行即时修正.通过仿真计算,对网格大小不同的地形匹配区提出了地形匹配区最大航向角偏差的精度要求.结果显示对误差漂移起到了明显的修正效果,为进一步研究减小制导工具误差的途径提供了新的思路和方法.

Research on Error Coefficient Divided of Cruise Missile Gyroscope Excursion

Take cruise phase as object under research,and based on the analysis of the influence of gyroscope excursion error impact on the apparent acceleration,the feasibility of separating the gyroscope error coefficient was analyzed,the precision of the IMU error coefficient according to precision and distance of different matching area with different sizing grid was proposed.The result of modifying the gyroscope excursion error is very obvious,which provides the basis for further study of the means of decreasing ...
