| 摘 要： | 针对微动研究中微多普勒特征多表现为正弦调频信号的特点,首先在时频域采用时频分析的方法预估计信号的类别和相关参数范围,进而在时域通过相关法搜索相关参数对多分量正弦调频信号进行分离,最后通过仿真验证了该方法的有效性。

| Abstract: | According to study of the micro-motion in which the micro-Doppler feature is mostly shown Sinusoidal frequency modulation(SFM) signals, firstly time-frequency analysis method is used to estimate signal category and the range of related parameters in time-frequency plane, furthermore correlation searching method is used to search related parameters for separating SFM signals, finally, simulation demonstrates the validity of the method. |
