| 摘 要： | 为了明确传感器配置形式及传感器数量对定位精度的影响,在全局坐标系下对多站三角定位中样本均值的定位性能进行了分析.首先根据一致性的定义研究了交点间的相关性及切比雪夫条件,进而指出多站三角定位中的样本均值是一种非一致性估计；然后结合传感器配置形式对定位精度的影响,分析了样本均值近似具有一致性的条件；最后讨论了一致性与多站定...

| Abstract: | To clarify the effect of sensor allocation form and the number of sensors on the localization precision,the localization performance of sample mean in multi-sensor triangulation localization is analyzed in the global coordinate system.First,the correlation between intersections and the Chebyshev condition is studied according to the consistency definition,which indicates that the sample mean in multi-sensor triangulation localization is a kind of inconsistency estimator.Second,combined with the effect of se... |
