Extraction of radar LFM signal parameter based on B-distribution

摘要

Linear Frequency Modulation (LFM) signal is an important signal format in radar signal processing field. Aimed at the characters of radar LFM signal, the B-distribution analysis method can be applied to descript it in this paper. On the basis of that, the Erosion transform can be utilized to highlight the characters of radar LFM signal, and Hough transform is employed to extract LFM signal parameter. The effectiveness and feasibility of proposed method can be proved by simulation results.
