| 摘 要： | 针对常规时频方法用于多分量信号分析的不足,基于时频重排方法克服多分量信号交叉项干扰和时频聚集性之间的矛盾且具有较好抗噪声性能的特点,在对时频重排原理进行综述的基础上,将其用于对多分量辐射源信号进行时频分析,并与其它方法进行了比较。仿真实验表明,时频重排方法不仅提高了时频聚集性,有效抑制了多分量的交叉项干扰,具有较好的抗噪声性能。

| Abstract: | Conventional time-frequency analysis methods are exposed to some limitations in analyzing multi-component signal.The method based on time-frequency reassignment not only overcomes the contradiction between the cross terms of multi-component signal and the approximate time-frequency centering,but also is robust to noise.The principle and application of time-frequency reassignment are summarized,and the multi-component radiator signal analysis is made based on the time-frequency reassignment and other methods.The simulation results show that the time-frequency reassignment method has comprehensive advantages. |
