Abstract :
Aiming at the shortly SNR capability of wavelet-ridge in extracting in-pulse features of LFM signal, in this paper, a time-frequency associated analyzed method based on wavelet transform and time-frequency reassignment is proposed‥ The method is based on LFM´s wavelet scalogram, and combined with time-frequency reassignment and time-frequency ridge. With the help of time-frequency reassignment in improving the time-frequency agglomeration of representations, the SNR capability of wavelet-ridge is enhanced. The result of the emulation experiments approved the feasibility of this method.
