| Abstract: | A method for the characteristic parameter estimation of the frequency-hopping signals jump cycle,transition time,and frequency was described based on the differential nature of frequency-hopping.Compared to the traditional maximum smoothed pseudo Wigner-Ville distribution,the proposed method has high accuracy of parameter estimation and reliability of detection at transition time.The validation of the proposed method was demonstrated in the simulation results and performance analysis. |

| Keywords: | frequency-hopping parameter estimation frequency differential time-frequency analysis |
