摘要
为解决电视跟踪系统中由于脱靶量滞后存在降低系统跟踪精度的问题,在电视跟踪等效复合控制系统中提出了一种改进的卡尔曼滤波算法——电视跟踪延迟卡尔曼滤波算法,以对脱靶量滞后信号进行补偿.并在电视跟踪等效复合控制系统中对该算法进行了仿真实验.实验结果证明:①该算法在电视跟踪等效复合控制系统中是有效的;②该算法比以往的无延迟卡尔曼滤波算法和脱靶量延迟补偿滤波算法更有效地改善了速度预测误差,减小了跟踪误差,从而提高了电视跟踪系统的跟踪精度.
A TV-tracking delay Kalman filter algorithm was put forward in order to improve the tracking precision in TV tracking systems by compensating miss distance signals. Simulation experiments were carried out in the equivalent compound control of TV tracking system. The simulation results indicated that comparing the traditional algorithm no-delay Kalman filter with the miss-distance-delay-compensation filter, this algorithm not only can improve velocity predicting error more effectively, but also can reduce tracking error, and then the tracking precision of TV tracking systems is improved.
