提高捷联惯组使用精度的方法研究

针对导弹武器捷联惯组使用精度不高的问题,提出了通过射前标定和误差系数补偿修正技术来提高其使用精度.不借助任何外部工具,完全依靠导弹自身提供的信息,射前标定11个误差系数,利用单次通电特性及等效补偿和落点偏差二次修正技术来减小落点偏差.弹道仿真结果表明,射前标定方法结合误差系数补偿修正技术能够有效地提高导弹的命中精度.

Research on the Method to Improve the Performance Accuracy of SIMU

Aiming at the performance accuracy problem of strapdown inertial measurement unit (SIMU), a method combined pre-launching calibration with error coefficient compensation and amendment technology was used to improve the performance accuracy. Depends on the information supplied by missile itself, 11 error coefficients can be calibrated before launching. Pre-launching compensation technique and quadric modification technique of landing error are introduced to reduce the landing error. The ballistic emulation results show that this method can effectively improve the hitting accuracy.
