Estimation of LFM signal parameters using RD compressed sampling and the DFRFT dictionary

Estimation of LFM signal parameters using RD compressed sampling and the DFRFT dictionary

Abstract In this paper, a method combining random demodulator (RD) and discrete fractional Fourier transform (DFRFT) dictionary is suggested to directly estimate the parameters of linear frequency modulation (LFM) signals from compressed sampling data. First, the RD system parameters are modified in...
