摘要：
In the paper, an analysis method of frequency-hopped (FH) signals based on time-frequency presentation is proposed which makes use of nonstationary quality of frequency-hopped signals Using the Wigner-Ville time-frequency analysis method, the parameter of FH signals such as hop duration, hop timing and hopping frequency can be estimated without knowing any prior knowledge. In the paper, a comparison of STFT, WVD, SPWVD used for FH signals demonstrates that SPWVD is an effective method for reducing the crossterms.
