摘　　要：推广的卡尔曼滤波器能根据雷达测量数据较好地跟踪飞行弹丸,并估计出有用参数,但动态方程和量测方程的线性化会给滤波和估值带来一定的误差。该文讨论了用单步迭代滤波来降低动态方程的线性化给弹丸跟踪滤波器带来的滤波和估值误差。The extended kalman filter can be used to track the fly-ing shbll quite well according to the measurements, and estimate theuseful parameters. However, the linearization of the dynamic andmeasurement equations results in errors in the filtering and estima-tion. This paper discusses a method for reducing the errors in thetracking filter by use of the single step iteration filtering.
