Based upon the nonzero mean-value time correlation model,a sliding acceleration meanvalue model and algorithm using two Kalman filters in series is put forward.The first filter is designed to cope with all possible target maneuvers and gives out a sliding mean-value of acceleration. Using the sliding mean-value as the input,the parameter of the second filter can be controlled adaptively to match the real states of the maneuvering target. This method widen the changable range of target maneuvering acceleration...

Based upon the nonzero mean-value time correlation model,a sliding acceleration meanvalue model and algorithm using two Kalman filters in series is put forward.The first filter is designed to cope with all possible target maneuvers and gives out a sliding mean-value of acceleration. Using the sliding mean-value as the input,the parameter of the second filter can be controlled adaptively to match the real states of the maneuvering target. This method widen the changable range of target maneuvering acceleration with high-precision of state estimation comparing with the ordinary non7ero mean-value time correlation model,such as"current"model.There are also no problems of the correlated measurement noise and correlated estimates of the two filters in early research work.Results from computer simulations are included to demonstrate the performance.

现代机动目标跟踪的困难来自跟踪的快速性与精度在一定计算负荷约束下的协调难以令人满意,考虑依次处理快速性与精度的方案,采用滑动均值均匀分布描述目标的随机机动特性,分别采用宽带的均值预估滤波器和窄带的跟踪滤波器串联,实现机动加速度大范围变动或突变的精确、快速跟踪.双滤波器的计算量适中,易于工程实现.对各种运动形式进行计算机模拟表明,这类算法对高度机动或弱机动或无机动均可给出较好的目标位置、速度及加速度估值.

The NWP fields of T.H.U.V. of NMC's T63, T106 and ECMWF's numerical model were separtely interpoleted into 108 meteorological stations. The interpoleted results were used as predicting factors to establish predicting equations of max. and min. tempreture by means of PPM, MOS and KF filter methods. With the above predicted results, the second filter consensus forecast and perfect consensus forecast were made, and the Temperatute Forecasting System for Every County by the provincial meteorological observatory...

The NWP fields of T.H.U.V. of NMC's T63, T106 and ECMWF's numerical model were separtely interpoleted into 108 meteorological stations. The interpoleted results were used as predicting factors to establish predicting equations of max. and min. tempreture by means of PPM, MOS and KF filter methods. With the above predicted results, the second filter consensus forecast and perfect consensus forecast were made, and the Temperatute Forecasting System for Every County by the provincial meteorological observatory based on the NWP product was developed. The operational practics from June to November in 1997 proved that the system showed good predicting results.
