Biography

Pascal Aubry obtained the MSc degree in electronics and microwaves from the Pierre et Marie Curie University (Paris 6) in 1993. After a one-year traineeship in antenna measurements at the European Space Research and Technology Centre, he joined TU Delft's International Research Centre for Telecommunication and Radar in 1997. There, he developed automated measurement software for the outdoors, indoors, and ground penetrating radar antenna test ranges. He is involved in the testing of antennas and radar systems as well as designing experimental setups to support research in domains such as landmine detection, concealed weapon detection, UWB radar imaging, and coloured waveforms for MIMO radar, for domestic and European projects. In addition, he supervises the lab sessions for many of the Microwave Sensing, Signals and Systems group courses. He co-authored over 50 peer-reviewed international journal papers and conference proceedings.

  1. 3-D Short-Range Imaging With Irregular MIMO Arrays Using NUFFT-Based Range Migration Algorithm

    IEEE Transactions on Geoscience and Remote Sensing,
    Volume 58, Issue 7, pp. 4730-4742, July 2020. DOI: 10.1109/TGRS.2020.2966368

    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.
