The detection method for linear frequency modulation(LFM) based on Wigner-Hough transformation(WHT) is summarized and the signal-to-noise ratio(SNR) expression for WHT in the additive gaussian white noise environment.On this basis a relative detection method based on WHT is proposed,and the expression for relative detection quantity is given.Simulation results show the proposed method can effectively suppress gaussian white noise and improve the detection performance for LFM signals.
