Parameter Estimation of Frequency Hopping Signals Based on Time Frequency Analysis

摘要：

　　Frequency hopping signal is analyzed in this paper using various time frequency analysis methods,including short time Fourier transform (STTT),Wigner-Ville distribution (WVD) and its improvements.By comparing the hop-ping patterns derived from these methods,spectrogram (SP) is chosen to estimate the hopping period,hopping timing and hopping frequency,as well as to obtain some valuable measurement results.Finally,a practical method is proposed to test the parameters of frequency hopping signals.
