摘　　要：为解决目标跟踪精度与观测时间间隔的矛盾,提出了一种基于目标状态估计协方差控制的观测时间确定算法.该算法以卡尔曼滤波器作为状态估计工具,根据跟踪精度要求设定目标估计状态协方差上限,通过目标估计状态协方差来控制观测时间间隔,从而实现对目标的优化观测.仿真结果验证了算法的有效性。To solve the contradiction between target tracking accuracy and observation interval, an algorithm of calculating observation time based on target estimate covariance control was presented. Using a Kalman filter as the state estimation tool, setting the threshold of target estimate covariance in terms of the target tracking accuracy, and controlling observation interval by target estimate covariance, the algorithm achieved the goal of optimal observation of targets. The effectiveness of the proposed algorithm is shown by simulation results.
