A New HRRP Reconstruction Method based on Joint Sparse Model

At present, most of the high resolution range profile reconstruction methods are based on a single echo signal, without considering the relationship between all the echo signals. In this paper, we consider the sparse feature of echo signal, and propose a method of high resolution range profile reconstruction based on joint sparse model. The method can not only improve the accuracy of the reconstruction, but also reduce the number of the reconstructed volume, and have strong anti-noise performance. Finally, the advantages of the proposed method in this paper are demonstrated by simulation and analysis.
