摘要 总结了基于Wigner-Hough变换的LFM信号检测方法,推导了加性高斯白噪声背景下的Wigner-Hough变换信噪比公式,在此基础上,提出了基于相对判决准则的Wigner-Hough变换检测方法,给出了相对判决量的计算公式。仿真结果表明,在信噪比较低时,该方法可有效抑制高斯白噪声,实现LFM信号的检测。 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.
