摘　　要：介绍了测量融合的思想,讨论了基于线性均方估计和极大似然估计的测量融合算法,在其基础上提出了考虑飞行参数统计信息的测量融合方法,并以捷联惯导/GPS/罗兰 C/Doppler 组合导航系统为例,研究了测量融合在组合导航系统中的应用。最后采用蒙特卡洛方法进行了仿真,仿真结果表明,与基于极大似然估计的测量融合算法相比,采用本文算法的组合导航系统具有更高精度。The idea of measurement fusion is introduced.Two measurement fusion algorithms based on linear mean square estimator and maximum likelihood estimator are discussed,on the basis of which a measurement fusion method using statistical information of flight parameters is proposed.Taking SINS/GPS/Loran-C/Doppler for an example,the measurement fusion algorithm of integrated navigation system is analyzed.The simulation result using the Monte Carlo method suggests that compared with the algorithm based on maximum l...
