Blind parameter estimation of low probability of intercept waveforms

A novel algorithm to estimate the parameter of low probability of intercept waveforms is presented, based on RAT, de-chirp and FRFT. Except for carrier frequency and chirp rate of triangular linear frequency modulation continue waveform (TLFMCW), modulation bandwidth and modulation period are also given. Finally the simulation results indicate that this method can provide good estimation performance even in low SNR.
