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。

Aiming at the signal processing problems that exist in online fault diagnosis for train running gear, based on discussing the principle of characteristic spectrum analysis, a method of full period and uniform angle sampling is applied, which transfers the vibration signal from time domain into angular domain. The angular domain signal is transferred into corresponding characteristic spectrum using FFT. Through spectrum estimation and analysis, fault characteristic spectrum values of running gear components are acquired to distinguish their faults.
