对匀速直线运动目标跟踪的转换坐标卡尔曼滤波算法

文章根据某型雷达对空间匀速直线运动目标的跟踪要求，采用了转换坐标卡尔曼滤波跟踪算法．在转换坐标卡尔曼滤波跟踪算法中，球坐标系下互相独立的观测噪声变换到直角坐标系下时将变成相关噪声，在解出此相关噪声的方差后即可按标准的卡尔曼滤波算法对目标进行跟踪，仿真结果显示，该算法收敛迅速，精度可以满足雷达对空间机动目标的跟踪要求．

Convert Measurements Kalman Filtering Algorithm for CV Target Tracking

To meet requirement of tracking a CV target,a convert measurements Kalman Filter (CMKF) is used.In CMKF algorithm, the uncorrelated observation errors become correlated with the measurements under polar coordinate.When the deviations of the correlated observation errors are resolved, we can use the standard Kalman filter to tracking the target precisely. Simulation results indicate that, the algorithm converges quickly and can track the target with the required accuracy.
