摘要
在三维空间中推导了转换测量卡尔曼滤波算法 ,得到了在目标真实位置已知的条件下去偏转换测量值误差方差的表达式及在测量值已知条件下去偏转换测量值方差的表达式 ,并给出了在机动目标跟踪中 ,预测值与量测值的选择准则。运用“当前”机动模型和此算法给出了机动目标的仿真 ,取得了较好的跟踪效果。
This paper derived the converted measurement Kalman filtering algorithm(CMKFA) in 3-dimensional space.The error covarinace of debiased converted measurements based on target's ture position is given,and the error covariance of debiased converted measurements based on measurements is also obtained.A method about how to choose the optimum data between measurements data and prediction data is presented A maneuvering target tracking application is simulated by using this algorithm and the 'Current Statistical'model,the tracking accuracy is well.
