摘要：
Aiming at the resolution contradiction between time and frequency in frequency-hopping (FH) signal parameter estimation, a new FH signal parameter estimation method based on STFT is proposed by analyzing the influence of window function of STFT on the time-frequency spectrum. The parameter of FH signal can be extracted from the parameter of sliding window directly, avoiding the influence of time-frequency spectrum on the accuracy of estimation. The key point of this method is to seek the time-frequency spectrum which has the best time-frequency concentration and get the parameter of target sliding window by changing the beginning time and the width of the sliding window. Simulation results show the method is efficient to estimate the parameter of FH signal.
