摘　　要：基于无线传感器网络,对目标定位跟踪应用进行了研究。在对目标定位跟踪时,如何既保证跟踪精度又能有效降低能量消耗,针对这个问题,提出了一种简便的加权坐标质心定位方法,通过对目标的定位,给出了一种基于测量信息的跟踪方法,方法实现简单。性能分析表明:提出的定位跟踪方法能有效地降低能量消耗,延长节点和网络寿命,基本可以满足战场目标跟踪需求。Based on the wireless sensor networks ,the localization of target track application is researched. When localization of target track is made, how both can the guarantee tracking accuracy and reduce the energy consumption effectively, in view of this question, one simple weighting coordinates center of mass localization method is proposed, through the goal localization, one kind track method based on the survey information is given, the method realization is simple. The performance analysis indicates, the proposed localization track method can effectively, reduce the energy consumption, extend the node and the network life, basic may meet the needs of the battlefield target tracking.
