The extended Kalman filter(EKF) and converted measurement Kalman filter(CMKF) have been widely used in radar target tracking.

在非线性量测的情况下，EKF和CMKF得到了广泛的应用。

However, it has been found that the performance of CMKF degrades considerably when cross-range measurement errors of the target position are large.

然而，当目标位置的互距离测量误差比较大时，CMKF的性能将急剧下降。
