一阶自相关 meaning in Chinese

first operation
first-order autocorrelation

And in allusion to the shortcomings on the fitting of noises by least square , a new procedure is presented to modify the estimations of model parameter of the noise . it can control the effects of the correlation noise of except for first order self - correlation noise . using the model the error of gps / ins integrated navigation system is estimated
再次，针对卡尔曼滤波方程的前提条件不满足而影响导航系统的精度的问题，应用时间序列分析理论提出了一种改进的噪声模型参数估计算法，对此算法进行建模，仿真结果表明，该算法能有效的控制一阶自相关特性以外的噪声对参数模型估计的影响，提高卡尔曼滤波精度。
