Wang, J. (author), Aubry, P.J. (author), Yarovoy, Alexander (author)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...journal article 2020

Wang, J. (author), Aubry, P.J. (author), Yarovoy, Alexander (author)Ground penetrating radar imaging from the data acquired with arbitrarily oriented dipole-like antennas is considered. To take into account variations of antenna orientations resulting in spatial rotation of antenna radiation patterns and polarizations of transmitted fields, the full-wave method that accounts for the near-, intermediate-, and...journal article 2018

Wang, J. (author), Aubry, P.J. (author), Yarovoy, Alexander (author)In this communication, a novel approach to rotated antenna array topology design is proposed for fully polarimetric short-range imaging. The rotated antenna array proposed acquires two co-pol and one cross-pol signals in terms of the “local” polarization basis by means of three antenna pairs. Then, the fully polarimetric signals in a global...journal article 2018

Wang, J. (author), Aubry, P.J. (author), Yarovoy, Alexander (author)A matrix-pencil based wavenumber-domain multiband fusion approach is proposed for improved microwave imaging. The suggested fusion approach is based on the fact from the Born approximation that the wavenumber-domain signal in a given scattering direction can be represented as a sum of the same number of contributions over the whole bandwidth....conference paper 2018

Wang, J. (author), Aubry, P.J. (author), Yarovoy, Alexander (author)In this paper, a wavenumber-domain matrix-pencil-based multiband signal fusion approach was proposed for multiband microwave imaging. The approach proposed is based on the Born approximation of the field scattered from a target resulting in the fact that in a given scattering direction, the scattered field can be represented over the whole...journal article 2018

Wang, J. (author), Aubry, P.J. (author), Yarovoy, Alexander (author)A novel approach to full-polarimetric short-range imaging with rotating arrays is proposed. Instead of taking advantage of all four possible combinations of the polarizations of transmit and receive antennas as in the typical full-polarimetric imaging systems, the suggested antenna array acquires three different co-polarized measurements at...journal article 2016
