    Abstract: ... 3-D imaging with irregular planar multiple-input-multiple-output (MIMO) arrays is discussed. Due to signal acquisition on irregular spatial sampling grids by using these antenna arrays, the fast Fourier transform (FFT)-based imaging algorithms cannot readily be used for image formation. To avoid the application of computationally intensive coherent summation algorithms such as filtered backprojection or Kirchhoff migration, we propose a nonuniform FFT (NUFFT)-based MIMO Range Migration Algorithm (i.e., NUFFT-based MIMO-RMA) for efficient microwave imaging. The algorithm exploits NUFFT to reconstruct the wavenumber–domain spectra related to each Fourier frequency. It is generic and applicable to 3-D imaging with irregular planar MIMO arrays. The effects of irregular spatial sampling and signal bandwidth on the imaging performance and computational efficiency of the proposed algorithm are analyzed. Finally, some numerical simulations and experimental results are presented to demonstrate the performance of the proposed imaging algorithm.

    Abstract: ... The expansion of microwave imaging applications in various fields proposes increasingly higher requirements (including spatial resolution, dynamic range, and signal-to-noise ratio) for microwave imaging systems. To achieve high-quality imaging, microwave imaging systems generally exploit spatial-, frequency- and polarization-diversities to probe objects of interest for information extraction. In practice, they are implemented by using array-, wideband/Ultra-wideband (UWB)-and polarimetry-techniques. So properly exploring these techniques is of great importance to design an advanced microwave imaging system. A motivation for the research presented in the thesis is to develop a ground penetrating radar (GPR) system to predict hazards ahead of tunnel boring machines (TBM) during tunnel excavation. In this circumstance, GPR antennas are mounted on the cutter-head of a TBM. With the rotation of the TBM cutter-head, GPR antennas collect electromagnetic (EM) signals over a synthetic circular aperture, which leads to the Radial-scanned Synthetic Aperture Radar (RadSAR). The rotation of the antenna array benefits the formation of the RadSAR but makes it distinct from traditional SAR modalities as well
