3模型、2模型的交互多模型算法与普通卡尔曼滤波算法在跟踪机动目标的时候的性能比较-3 models, 2 models of interactive multi-model algorithm and the ordinary Kalman filter algorithm in maneuvering target tracking performance when compared

在matlab中利用当前模型，实现对GPS数据的动态滤波-In matlab using the current model, to achieve dynamic filtering of GPS data

北斗GPS双模在利用“当前”统计模型并利用kalman滤波时，其系统噪声和观测噪声未知且时变，而且加速度上下限不能自适应于未知运动规律的无人飞行器当前加速度，导致导航精度降低。该程序是相应的MATLAB仿真程序。(Beidou GPS dual mode uses the "current" statistical model and the Kalman filter. Its system noise and observation noise are unknown a
