Some notes on parameter estimation in a class of linear models with an error vector having multivariate t distribution 分布的一类线性模型下参数估计的若干注记
This method constructs covariance matrix by utilizing data vectors in different range lines and projects phase error vector into noise sub - space which is formed by eigendecomposing the covariance matrix 该方法利用不同距离单元的观测矢量构造协方差矩阵,然后通过对协方差矩阵特征分解得到噪声子空间,最后将相位误差矢量向噪声子空间投影来估计多普勒调频率。
