For the problem in DOA estimation of LFM signals that the ordinarily arithmetic often need a large number of samples and can't gain ideal effect in condition of low SNR.The paper proposed a new method of DOA estimation of linear frequency modulation(LFM) signal based on CS theory.Experimental simulation provides a proof of the basic ideas of CS theory and the feasibility in LFM signal DOA estimation.
