摘　　要：无线传感器网络能够实时检测和采集网络分布区域内的各种监测对象的信息,因此基于无线传感器网络的目标检测与跟踪系统研究成为当前的研究热点。在研究时差到达(TDOA)技术的基础上,设计了一种基于无线传感器网络的超声波和无线电相结合的小范围移动目标检测与跟踪系统,用基于距离和角度计算来精确定位,并根据定位信息绘制其轨迹图,达到检测与跟踪的目的。理论及实践证明了该方案的有效性,并有着广泛的应用前景。Wireless sensor network （WSN） is able to instantly monitor and collect all kinds of information for different objects in the network distributed area. A lot of researches focus on target detecting and tracking system based on WSN. One kind of short-range mobile target detecting and tracking system based on WSN is researched and designed by using ultrasonic radio positioning technology. Location computing based on distance and angle can implement precise position and draw track of object, The theoretic analysis and practice show that the scheme is highly effective and can be utilized in a broad foreground.
