单传感器无序量测反馈估计算法

Single sensor OOSM feedback estimation algorithm

针对单传感器的无序量测问题,提出一种处理无序量测的反馈估计算法。该算法一旦出现延迟无序量测,融合中心将最后更新的状态估计回传至传感器进行若干采样周期的卡尔曼滤波,并将状态更新传至融合中心。该算法可保证实时性,具有良好的估计精度,仿真结果验证了算法的有效性。

Aiming at single sensor OOSM problem, an OOSM feedback estimation algorithm is proposed. Once OOSM oc- curs, the last update state will be sent back to the local sensor for sampling some periods with Kalman filter by the fusion center. The proposed algorithm can guarantee real-time, and good estimation accuracy is obtained, simulation results show the algorithm is effective.
