Abstract：The Short-time Fourier Transform(STFT)can both have the time and frequency resolution at the same time.In or?der to solve this problem,a new joint algorithm that is based on parameter estimation of frequency-hopping signals is proposed. First,STFT with short window is obtained.Then,coarse estimation of hopping time is extracted from the time-frequency ridge of ST?FT. And the accurate estimation of hopping time is extracted from the obtained coarse estimation which is corrected by the least squares method.Finally,the Burg algorithm is used to estimate the frequency of the signal between the two hopping time.Theoreti?cal analysis and simulation results demonstrate that the proposed method can effectively and feasibly estimate parameter of frequen?cy-hopping signals.
