Title: THz 3-D SAR Sparse Imaging with 2-D Pseudo-random Array 

Abstract: For real-time Terahertz (THz) three-dimensional (3-D) imaging, spatially 2-D sparse sampling is one of the most promising techniques to reduce the heavy complexity. We propose a new THz 3-D synthetic-aperture-radar (SAR) sparse imaging method by establishing a 2-D pseudorandom array. The proposed method consists of sparse sampling-pattern design and sparse-imaging processing, to answer what the under-sampling pattern is and how much the number of samples can be thinned by the current sparse imaging. The constant, showing the extent to which our proposed method can reduce the number of samples is numerically estimated through simulations. The imaging results obtained by the numerical and experimental simulations demonstrate that our proposed method can offer performance comparable to the dense sampling by Nyquist law, even when the sparse degree is thinned to 30%.
