卡尔曼滤波在对离散线性系统进行最优化的时候用到系统的预测方程和测量方程,但是只考虑了最简单的线性关系,即系统预测方程线性化,由于变量的均值和方差只能进行线性运算,那么当系统预测方程非线性化的时候该怎样计算预测值的方差呢? UKF就是为了研究解决这种非线性关系的。-Kalman filter used in optimization of discrete linear systems prediction and measurement equations of the system, but

根据伪随机序列理论,由混合同余法产生均匀分布的随机数,进而根据中心极限定理来产生高斯噪声。
分析所产生的均匀分布和高斯分布随机信号的均值、方差、自相关等数字特征,估计其概率密度函数并进行分析,估计其功率谱密度并进行分析。说明该高斯噪声是否符合白噪声特性。
对该高斯噪声进行FIR低通滤波,估计输出低通型限带白噪声的功率谱、相关时间等,并结合白噪声通过线性系统相关理论来进行分析。
