Petrov, N. (author), le Chevalier, F. (author), Yarovoy, Alexander (author)Adaptive detection of fast moving targets by means of high range resolution radar is considered. It is assumed that a fast-moving target of interest has a few range cells migration during the coherent processing interval and the clutter power fluctuates rapidly along the range. Therefore, the target competes with the clutter responses in a few...conference paper 2019

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
