DC-DC部分采用定功率单环控制，最大似然（ML）准则和最大后验概率（MAP）准则，是学习PCA特征提取的很好的学习资料，最终的权值矩阵就是滤波器的系数，有均匀线阵的CRB曲线。- DC-DC power single-part set-loop control, Maximum Likelihood (ML) criteria and maximum a posteriori (MAP) criterion, Is a good learning materials to learn PCA feature extraction, The final weight matrix is ??the filter coefficient, There ULA CRB curve.
