摘要
根据飞机局部散射机理与局部散射RCS模型,理论分析了飞机旋转部件的微多普勒回波模型。通过雷达回波的频谱特征分析,提出了一种目标微多普勒特征的提取方法。利用实测数据进行验证,表明该微多普勒特征提取方法是有效可行的。
The micro-Doppler echo model for the rotating parts of the aircraft is analyzed theoretically based on the aircraft local scattering theory and RCS model. According to the spectrum signature analysis of radar echoes,a method of micro-Doppler feature extraction is proposed. Finally,the method is verified to be effective and feasible using the actual test data.
