对进入监控区域的运动目标进行探测跟踪是无线传感器网络的一项重要功能，以传感器模型和Exposure模型为基础，分析了目标的运动速度与检测可能性之间的关系，给出了不可测临界速度和完全可测临界速度的定义及其与传感器参数之间的函数关系；通过仿真，验证了理论的准确性，这为根据实际需要进行传感器节点布设和传感器的参数设计提供了参考。

The detection and tracking to the moving target in surveillance region is an important function of wireless sensor network. Based on the sensor model and Exposure model,this paper analyses the relation-ship between speed and detection probability of target,definition of the undetectable speed and completely measured critical velocity,and their function relationship with the sensor parameters. Through the simula-tion,the accuracy is verified. It provides the reference for the actual needs and design parameters of sensor nodes.
