Abstract Compressive sensing technique has been shown to be able to reduce effectively the data rate of high- resolution radar imaging system. A phase-preserving range compression algorithm based on Compressive Sensing (CS) technique is proposed, after analyzing the sparse characteristics of complex base-band echo signal from a target using chirp signal as transmitted signal. Based on this range compression algorithm, a 2D imaging scheme is established, i.e. performing range compression by using CS technique and performing azimuth compression by using traditional technique. The effectiveness of the 2D imaging scheme is tested through processing both simulated data and real radar data.
