| 摘 要： | 研究了可用于多传感器组合导航系统的两级分布式最优融合算法,以理论的形式证明了在有、无信息反馈的情况下最终的融合结果是等价的与最优的。仿真结果在验证上述理论的情况下,也说明了来自融合中心的反馈信息可明显提高子滤波的滤波性能。

| Abstract: | The two-level distributed optimal fusion algorithm which can be used in multi-sensor integrated navigation system is studied,and the theoretical mode is approved.The final fusion results with feedback and without feedback information are equivalent and optimal.The simulated results verify the above theory,and also illustrate that the feedback information from the fusion centre can obviously increase the filtering performance of every sub-filter. |
