本文在对杂波协方差矩阵的特征值、阵特征向量做出分析的基础上,讨论了无信噪比损失的降维的充要条件,并给出了一种满足该条件的降维变换阵的构造方法.最后基于一组Mountaintop数据对文中提出的算法作出了验证
The selection of the transform matrix has an effect on the output signal to interference plus noise ratio. Itcan achieve its upper bound when transform matrix is selected in a special form. So
a new kind of rank-reduced STAP is proposed. When covdariance matrix is known
it is the same as the full dimension optimal STAP. When covariance matrix is unknown
it also has a good appearance.
