给出了一种利用磁传感器进行方位估计的扩展卡尔曼算法，该方法效果很好。-gives a magnetic position sensor is estimated that the extended Kalman algorithms, the method yielded good results.

The extended Kalman filter (EKF) has been widely used as a nonlinear filtering method for radar tracking problems. However, it has been found that in case cross-range measurement errors of the target position are large, the performance of the
