A new approach to eliminate the ranges dependence based on angular frequency shifting in space domain was presented, in which, the nonhomogeneity of clutter is removed and the blind area of target detection is reduced due to the fact that the clutter of all the compensated range cells in every channel is moved to the place of the clutter of the desired cell by the different angular frequency shifts being added into spatial data along all Doppler channels for every compensating range cell.

第七章针对非正侧视相控阵机载雷达，由于杂波在距离上呈现出严重的非均匀性，尤其是在近程这种依赖距离的杂波谱呈现的非均匀现象更为严重，使得用于计算自适应权的协方差矩阵不可能直接由距离单元数据统计平均来估计得到，否则STAP处理及其降维技术难以获得理想的杂波抑制性能和目标检测性能，甚至恶化。

The model of nonhomogeneous clutter environment is the precondition of the following research.3、Clutter non-homogeneity detector is studied, and a new clutter non-homogeneity detector is proposed by using frequency center idea for clutter spectrum shifting and nonhomogeneity of clutter power.

适合非均匀杂波环境的机载雷达接收数据模型为后续的适合于非均匀杂波环境的STAP方法提供了基础。3、研究了杂波非均匀检测器，针对杂波谱移动非均匀和杂波功率非均匀，提出了"频心"法杂波非均匀检测器。

To solve the problem, a knowledge aided space time adaptive processing scheme is presented, which incorporates knowledge sources of clutter with the general inner product nonhomogeneity detector in the secondary data selection of STAP.

该方法将待测距离单元杂波的先验知识与广义内积非同态检测器(general inner product nonhomogeneity detector， GIP NHD)结合，对训练样本进行有效选择。

The principal component method and the minor component method are recommended to reduce the computation of MNE and MPE respectively. Whether rank reduction conducted or not, STAP is always performed in a particular space which may be spanned or expressed by different sets of basis.

我们在第5章讨论了DFP结构上两种特征子空间降维方法，即最小功率特征对消和最小范数特征对消，这两种方法将权矢量约束在噪声子空间内，从而能够对消与噪声子空间正交的杂波分量。
