Efficient 3-D Near-Field MIMO-SAR Imaging for Irregular Scanning Geometries

Code to accompany our paper "Efficient 3-D Near-Field MIMO-SAR Imaging for Irregular Scanning Geometries" (arXiv, DOI).

• This code provides several examples for simulating multi-planar multistatic scenarios and recovering the image using the proposed algorithm (EMPM: Efficient Multis-Planar Multistatic) or conventional backprojection algorithm (BPA).
• This project relies on the Terhertz Imaging Toolbox with Interactive User Interface for simulation. The THz toolbox must be installed for any of this code to work.
• The work in this paper was extended in our follow-up works proposing data-driven algorithms for improving images reconstructed using the EMPM algorithm: "A Vision Transformer Approach for Efficient Near-Field SAR Super-Resolution under Array Perturbation" (arXiv, DOI) and "Efficient CNN-Based Super Resolution Algorithms for mmWave Mobile Radar Imaging" (arXiv, DOI).
