The thresholds for LFM signals recognition: a the average values of imag(ψ 3,3) against different 2 ranging from 8 to40 for different SNR values; b the average values of imag(ψ 3,3) versus SNR for different modulations for 2 = 40; c the average values of real(ψ 3,3) against different 2 ranging from 41 to500for different SNR values; d the average values of real(ψ 3,3) versus SNR for different kinds of signals for 2 = 41
