| 摘 要： | 为了提高多站无源定位精度,以LS算法的GDOP为基础对多站测向交叉定位的最佳配置形式进行了分析.指出当目标位于多传感器形成的闭合区域内、外侧时,其最佳配置形式是各相邻传感器间夹角相同,且传感器位于以目标位置(同时为坐标系原点)为圆心的外接圆上;如果在该最佳形式中没有对相邻夹角的限制,则LS算法可以达到方差最小意义下的最优估计;文中同时对最优估计及最佳配置条件下LS算法的一致性进行了分析.仿真结果验证了最佳配置形式的分析,并指出该形式可以应用到基于传感器管理的多站无源定位算法中.

| Abstract: | To improve multi-sensor passive localization precision,the optimal allocation form of multi-sensor bearing-only localization is analyzed from the perspective of the geometric dilution of precision (GDOP) of the least squares (LS) algorithm.This paper indicates that whether the target lies inside the closed region formed by the sensors or not,the optimal allocation is when each adjacent cut angle between a sensor pair is identical,and all sensors are located on the border of the circle that has the target (w... |
