| 摘 要： | 针对微动特征的有效分析和提取,研究了基于Radon变换的目标主体信号与微动信号分离方法。首先对回波信号进行时频变换,然后在时频平面上通过Radon变换来分离目标主体信号与微动信号,再通过逆Radon变换得到分离信号的时频分布,最后通过仿真验证了方法的有效性。

| Abstract: | For the effective extraction and analysis of the micro-Doppler feature, the separation method of the target main body signal and micro-motion signal based on the Radon transformation is discussed. Firstly, time-frequency transform of the echo signal is performed, and then the target main body signal and micro-motion signal is separated by the Radon transform in the time-frequency plane, furthermore the time-frequency distribution of separated signals is obtained by inverse Radon transform, finally, simulation demonstrates the validity of the method. |
