| 摘 要： | 本文采用定位的位置误差GDOP(Geometrical Dilution of Precision)作为优化对象,具体分析二维无源定位的可估计性优化问题,通过边估计边优化观测器运动的方法,以期在定位的各个时刻能得到最优的定位精度.本文还证明了在GDOP标准下,跟踪问题中的观测器运动寻优方法与其对应的定位问题相同.从而解决了在测角无源定位与跟踪中为了提高定位精度观测器如何进行自适应运动的问题.

| Abstract: | In bearings only tracking,observer maneuver is critical to ensure observability and to obtain an accurate target localization.In this paper,the author presents an adaptive observer maneuver control approach based on minimizing the GDOP of target localization,in order to achieve the best estimation accuracy at each second of localization process.The approach for optimizing observer course in target tracking is verified to be the same as in target location. |
