主要对扩展卡尔曼滤波(EKF)、无迹卡尔曼滤波(UKF)及改进无迹卡尔曼滤波(MAUKF)算法进行研究,研究了三种算法的基本原理和各自的特点。其中扩展卡尔曼滤波器是将卡尔曼滤波器局部线性化,其算法简单,计算量小,适用于弱非线性、高斯环境。无迹卡尔曼滤波器是用一系列确定样本来逼近状态的后验概率密度。改进无迹卡尔曼滤波算法在UKF的基础上引入衰减因子。-The thesis focuses on the extended Kalman filter (EKF), unscented Kalman f

无迹卡尔曼滤波UKF是重要的非线性滤波方法。它采用UT变换的方法,不再近似系统的非线性方程,它仍然用高斯随机变量表示状态分布,不过是用特定选择的样本点加以描述,每个点叫一个高斯点,它从系统状态的概率密度函数中取出;然后,按系统的真实模型演化,得到非线性演化后的σ点,使得样本均值和样本方差是真实均值和真实方差的好的近似。
在这个程序中,实现了基于UKF的滤波方法,并且建立了两种仿真环境进行实验。-Unscented Kalman filter UKF is an important nonli

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。
