Radar speech signal acquisition based on the millimeter wave radar is proposed to overcome the shortcomings of traditional speech acquisition methods. However, the signal quality is influenced by the device noise and sampling rate. In this paper, modified Compressed Sensing based method is proposed to enhance radar speech signal. Experimental results validate that the proposed method can improve the radar signal quality and reduce the noise.
