机动目标跟踪MS模型

A MS model for tracking maneuvering targets

针对Singer模型中人为设定参数的不合理性,对机动时间常数的倒数α和驱动白噪声方差σ2w进行估计,提出新的Modified Singer(MS)模型,并给出相应的参数自适应滤波算法。该模型在估计目标状态的同时,能够实时估计参数α及σ2w的值。仿真结果表明MS模型比Singer模型状态估计更精确,结果也更稳定。

Owing to setting up the values of the parameter α and δ^2 were artificially unreasonable in the Singer model, MS model instead of Singer model is proposed to adaptively estimate the state and the parameters. MS model can real-time estimate the valves and the state in the same time, the simulation results show that the MS model estimates more accurate and the estimation result is more stable.
