无线网络的出现使移动追踪并定位正在运动的目标变为可能,在多传感器网络中,测距定位是目标定位的一种常用手段.利用测距定位的移动追踪方法,根据移动传感器信源节点的信息及感知目标所得的测距数据,推算出目标的位置,由信源节点与目标节点的位置分剐确定各个信源节点的追踪方向,使移动传感器信源节点沿该方向追踪目标.但被追踪的目标本身也是移动点,再利用孤立求解的特性再次推算出目标的位置,如此循环往复,直至完成任务.通过在MATLAB环境中进行仿真的实验,表明该方法可使移动信源节点有效地追踪活动目标.

The emergence of wireless network makes tracking and locating the movable target become possible.Range-located is a popular means of target-located in the multi-sensor network.According to the information of mobile sensor nodes and the range data by apperceiving the target,in the method,the position of the target can be calculated.Then the tracked orientation of every source node can be located according to the position of source nodes and target nodes,so the target can be tracked by source nodes based on these orientation.Because the target is movable,it must recalculate its position by the isolated property,again and again,until the completion of tasks.The results of simulating experiment in MATLAB environment show that the method is more effective to track movable target by mobile source.
