虽然目前文献上有很多种图像形状描述子，但是可以归分为两大类：基于轮廓的形状描述子和基于区域的形状描述子。

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。
