Application of Time-Frequency Analysis Method Based on Signal Decomposition on Target Detection of High Frequency Surface Wave Radar

Renzhou Gui

Abstract

The time-frequency analysis based on signal decomposition is proposed,after comparing some conventional time-frequency analysis methods such as short-time Fourier transform(STFT) and Wigner-Ville distribution(WVD).The time-frequency analysis based on signal decomposition can avoid that the time and frequency resolution in STFT method cannot be improved at the same time and can solve the cross-term problem in WVD method,and the feasibility of the time-frequency method based on signal decomposition is proved by processing the actual data.
