弹载捷联惯导系统性能评估技术研究

Research on performance evaluation technology for missile-borne SINS

针对武器系统对弹载捷联惯导系统性能评估要求，对捷联惯导系统对准和导航精度分析方法展开研究，对比目前常用的固定区域平滑、固定点平滑算法的各自优缺点，特别设计了一种新的滤波算法利用导航段数据进行kalman滤波对惯导传递对准与导航误差进行评估；进行了算法仿真，证明了的算法设计的可行性与实用性；在有大量测数据的情况下设计了一种，统计方法对惯导性能记性统计计算，所设计的新的评估算法相对于固定区域平滑、固定点平滑算法，更实用、更具有工程应用价值。

According to the requirements of the performance evaluation of weapons systems for missile-borne SINS, The ac- curacy analysis method of SINS transfers alignment and navigation are researched. Comparison the fixed point and fixed in- terval smoothers algorithm the advantages and disadvantages, specially designed a new algorithm using the navigation seg- ment data kalman filtering for assessment of SINS transfer alignment and navigation error; software simulation of the algo- rithm was adopted, the simulation results proved that the design of evaluation algorithms for the fixed point and fixed inter- val smoothers algorithm more practical, more engineering value.
