摘　　要：针对电子侦察系统目标跟踪任务,提出一种结合预测误差门限和目标机动检测的跟踪数据率自适应调度算法。利用目标预测位置处的GDOP缩放值作为跟踪精度门限,在预测误差不超过该门限的约束下最大化回访周期。仿真结果证明该算法能够根据目标的运动状态自适应地选取合理的回访周期,可有效降低跟踪任务时间资源消耗,实现跟踪精度和时间资源利用率的良好折中。Aiming at target tracking task of electronic reconnaissance system,an update rate adaptive scheduling algorithm combining prediction error threshold with maneuvering detection is presented.Using the scaled GDOP of predicted target position as the tracking accuracy threshold,the revisiting period with the prediction error constrained by the threshold is maximized by the algorithm adaptively.Simulation validates the algorithm can adaptively select appropriate revisiting period according to target’s motion,effectively reduce the cost of time resource and provide good tradeoff between tracking accuracy and time resource utilization efficiency.
