%X Through the analysis of fractional Fourier transform of the Linear Frequency Modulation (LFM) signal, a LFM interference suppression algorithm using Time-Frequency Windowed-Short Time Fourier Transform (TFW-STFT) is proposed. Because the energy of LFM interference can be concentrated into a very narrow band in frequency domain by the time-frequency window, the impact made on the signal by TFW-STFT is lighter than the STFT. Simulation results show that the SNR loss and the BER performance of the proposed algorithm are evidently better than the STFT algorithm.
