摘要
针对宽波束高频地波雷达监测海面低速移动目标的工程应用要求,采用一种新的跟踪门预处理的联合概率数据关联方法对目标进行跟踪。基于数据关联性能评价函数和运动定理相结合的跟踪门规则能够减少跟踪门内非本目标的回波;在此基础上采用简化的联合概率数据关联算法对波门内的回波进行关联滤波,从而降低错误关联的概率并减小关联计算负荷;雷达实测数据分析表明,该方法计算量小,能够稳定、有效的实现高频地波雷达系统中的目标跟踪,适于工程应用。
According to the requirements of tracking ship targets with broad beam HF ground wave radar, this paper provides a new engineering data association filtering method based on tracking gate and cheap joint probability data association to track targets during the radar ＂s real-time sampling interval. A new optimal tracking gate algorithm based on the performance of data association and Law of Motion is presented in the method. The invalid measurements are reduced effectively by using the gate which leads to the decrease of association computation. The method is easily realized to track multiple targets in HFGWR system for its low computation. Its good tracking performance is proved by the analysis of experiments results.
