High Resolution RD Reconstruction for Two-dimension Sparse HF Radar

Abstract

Abstract.A novel high resolution range-Doppler (RD) reconstruction method for high frequency (HF) radar via compressed sensing (CS) is proposed. In this framework, discontinuous frequency sub-bands and incomplete pulse bursts are used to reconstruct high resolution range profiles (HRRPs) and Doppler spectrum simultaneously. The method is capable of effective suppression of sidelobes introduced by bandwidth discontinuity and preservation of temporal coherence of the signal in Doppler analysis despite the time samples deficiency. Simulation and experiment results have demonstrated the effectiveness of the proposed method.
