Then influences of frequency offset and observationinterval on symbol timing recovery system under this circumstance were studied.
针对这一特点，研究了加入卡尔曼滤波后频偏及观测时间长度对定时系统性能的影响。

To solve the contradiction between target tracking accuracy and observationinterval, an algorithm of calculating observation time based on target estimate covariance control was presented.
为解决目标跟踪精度与观测时间间隔的矛盾，提出了一种基于目标状态估计协方差控制的观测时间确定算法。
