Abstract
Aiming at the nonstationary and frequency variability of frequency-hopping signals,STFT is taken to analyse frequency-hopping signals.The period,time and frequency parameters of frequency-hopping signals is estimated based on STFT.Lastly,the influence of width of window to parameter estimation is analysed.The result of simulation shows that the characteristic parameters of frequency-hopping signals could be estimated by STFT,which is the foundation of HF signal classifying by communication scout system.关键词
