| 摘 要： | 在多传感器跟踪系统中，由于存在通信延迟等因素使得跟踪滤波器的传感器到达处理中心的时序被打乱，出现无序量测的情况．本文主要采用目前国际上用的较多直接更新法，即直接用延迟到达的量测更新目标状态，同时考虑输入噪声和过程噪声的相关性，给出了噪声相关情况下的无序量测的直接状态更新估计．最后又通过计算机仿真比较了丢弃延迟量测和直接更新法，验证了该算法具有更高的优越性，更具实际意义．

| Abstract: | This paper discusses the out-of-sequence measurement state estimate, and develops the optimal state update estimate algorithms of the 1-step-lag case when the processor noise and the measurement noise correlate. Simulation results verify the validity and feasibility of the algorithm. |
