statistic noise的意思|示意

In case of the noise statistic being unknown or variable, adaptive Kalman filter is used to get drift speed of each axle at each test position, and then drift parameter is calculated.

在噪声统计未知或时变的情况下，每个位置采用自适应卡尔曼滤波解算出平台各轴的漂移角速率，并在此基础上辨识出漂移参数。

A simple and effective adaptive filter is used to decrease statistic noise of the curve.

最后为了降低曲线的统计噪声，给出了一种简单适用的自适应滤波技术。

Because the system equation is changed with time, during the measurement, the statistic character of the system noise and the observation noise cannot be estimated or be determined accurately.

由于系统方程是时变的，在测量过程中，系统噪声和观测噪声的统计特性等很难精确地估计或测定，事实上很多误差模型都不能简单的设为白噪声。
