| 摘 要： | 根据近场目标的含义,使用二元传感器模型,通过数学分析和推导,以定理的形式表达得出了传感器网络近场目标的最小定位误差,其可以用于传感器网络对目标的协同跟踪,进而根据传感器位置,可以确定:在某一时刻,由哪些传感器对目标进行定位,在哪一段时间对目标进行跟踪。仿真结果说明了定理的正确性。

| Abstract: | Based on the meaning of near-field target and from arith analyse,we educe the least location error of near-field target which is put in forms of theorem using duality sensor model.It will be used in cooperative tracking in wireless sensor networks,and moreover,we can ascertain that,in a certain time,which sensors are used to localize target,and in which hour the sensors track target.Finally,the simulation experiment shows its validity. |
