Abstract：Aimed at the parameter extraction of Linear Frequency Modulation (LFM)signal,an novel pa-rameter extraction method is proposed in this paper based on Erosion transform and Hough transform. First,LFM signal is described by using B-distribution analysis method.On the basis of this,the Erosion transform is utilized to highlight the characters of radar LFM signal,and then Hough transform is em-ployed to extract LFM signal parameters.The simulation indicates that the method can not only extract the parameters of LFM signal in precision,but also has a good anti-noise performance.
