Abstract：Restricted by the current A/D sampling, parameter estimation of sub-sampling wideband Linear Frequency Modulated (LFM) signal has important research value. Based on that the LFM signal has approximate rectangular spectrum, the differentiation spectrum is used to extract the edge of sub-sampling LFM spectrum by Orthogonal Matching Pursuit (OMP) in this paper. It can estimate the initial frequency and final frequency of sub-sampling wideband LFM signal and has higher estimation precision. The effectiveness of this method is confirmed with numerical simulation.
