    摘要:

    脉冲多普勒雷达(PDR)是一个超宽带雷达系统,不仅能探测目标位置,也可通过多普勒效应测量其径向速度。然而,传统的雷达信号处理技术与极限计算和典型无线传感器微粒上的存储资源不相匹配。利用小型脉冲多普勒雷达作为传感器节点,通过设计一个新的目标跟踪系统来探索脉冲多普勒雷达和微型无线传感器节点的兼容性。该系统由几个PDR传感器节点组成,来检测移动目标的存在和位置,一个基站节点用来收集传感器节点的检测数据,一个算法来估计目标的位置。结果表明该系统有较小的偏差,可实现目标跟踪。

    Abstract:

    The pulse Doppler radar (PDR) is an ultra wideband radar system, not only can detect the target location, but also measure the radial velocity through the Doppler effect. However, the conventional radar signal processing techniques and the limit calculation don't match the storage resources of typical wireless sensor particle. By using miniature pulse Doppler radars as the sensor nodes, the compatibility of PDR with miniature wireless sensor nodes has been studied through the design of a new target tracking system. This system is composed of several PDR sensor nodes to detect the presence and position of the moving target, one base station node is used to collect the detection data from the sensor nodes, and an algorithm to estimate the location of the object. The results show that the system has smaller deviation, but it is enough to realize the target tracking.
