摘　　要：复杂背景下目标稳定跟踪是衡量雷达跟踪器性能的重要参考,而目标跟踪持续时间是其考察指标之一。提出一种基于Kalman滤波器的目标航迹平均跟踪周期数计算方法,并对两坐标雷达在不同点迹级目标检测概率、虚警概率、雷达测量精度、数据周期以及相应探测距离条件下的目标航迹平均跟踪周期数进行了仿真和分析。Stable tracking of radar targets in complex environment is a vital reference to evaluate the performance of a radar tracker,and target tracking duration is one of the indexes of the evaluation. A method for calculating the average tracking period of the target tracks is proposed based on the Kalman filter. In addition,the simulation and analysis of the average tracking period of the target tracks for 2 D radars are performed on the condition of different plot-level target detection probability,false alarm probability,radar measurement accuracy,data cycle and corresponding detection range.
