摘要： 本文针对射频(RF)信号的频率高、瞬变等特点，提出了一种基于S变换的射频信号检测方法。仿真结果表明，S变换具有很好的时频分析能力，能很好地分辩出射频信号的时频性能。
关键词: 射频信号, S变换, 时频分析
Abstract: It is hard to detect the timefrequency properties of RF signals because of their characteristics of high frequency and transience. A novel method focusing on the RF signals detection based on the Stranform is presented in the paper. MATLAB results show that the Stransform is unique in that it provides frequencydependent resolution, which correctly identifies the timefrequency performance of the RF signals.
Key words: RF signal;S tranform;timefrequency analysis
