摘要： 利用Fisher信息矩阵方法,研究了针对距离、到达时间和方位角三种测量方式下的最优传感器—目标几何定位与拓扑图形特征。仿真结果表明,通过对最优传感器—目标几何图形特征的分析,可以获得具有最优定位性能的传感器—目标几何拓扑;同时表明,最优几何拓扑一般不是唯一的。

Abstract: Considering the validity of received data,a novel information infusion and localization technology was presented for wireless multisensor based on optimal geometrical topology theory. The optimal sensor-target geometrical localization and topological characteristics were studied with three types of measurements including range-only,time of arrival,bearing-only. The results show that the sensor-target geometrical topology with optimal localization performance can be implemented by analyzing the sensor-target geometrical characteristics. And the optimal geometrical topology is usually not exclusive. Considerable research foundation was provided for understanding the essence of localization,tracking and navigation for wireless multisensor by intrinsic geometrical topology.
