Chen Gang · Journal of Hebei University · 2013
According to the question of detection for the linear frequency modulation(LFM) signal,basing on the characteristics of the LFM signal energy being concentrated on the time-frequency plane,a method of detection for LFM signal based on Radon-Wigner transform(RWT) is proposed.By analyzing the performance of detection,the signal-to-noise ratio of RWT exportation under noise background is received,and the detection probability in Gaussian white noise environment is derived.The results show that this method is efficiency for the LFM signal detection,and the detection performance is improved under low SNR conditions.
