摘要
在弹道导弹末制导中,由于多传感器组合导航系统的状态方程维数较大,因此应用集中滤波器处理会导致计算量大且容错性、可靠性不高。针对这种情况,采用无反馈模式的联邦滤波器,构建了GPS/SINS/SAR组合导航系统,并对其进行了仿真。仿真结果表明,该组合导航系统能较大地提高导弹的射击精度。
In terminal guidance of a ballistic missile, since the dimension of state equations of a multi-sensor integrated navigation system is great, the application of the centralized filter has the disadvantage of extreme capacity and the poor robust. Against this case,the non-feedback mode federal filter is adoped and the integrated navigation system with GPS/SINS/SAR is established in this paper. The mathematical results indicate the accuracy of gunnery of the missile can be largely increased by this algorithm.
