Neemat, S.A.M. (author), Krasnov, O.A. (author), van der Zwan, W.F. (author), Yarovoy, Alexander (author)Classical saw-tooth Frequency Modulated Continuous Wave (FMCW) radars experience a coupling between the maximum unambiguous Doppler-velocity interval, maximum operational range, range-resolution and processing gain. Operationally, a trade-off is often necessarily made between these parameters. In this paper, we propose a waveform and a...journal article 2020

Neemat, S.A.M. (author), Uysal, Faruk (author), Krasnov, O.A. (author), Yarovoy, Alexander (author)A reconfigurable range-Doppler processing method for FMCW radar is presented. By concatenating beat-frequency signals from more than one sweep, a continuous beat-frequency signal for the whole coherent processing interval (CPI) can be created. As a result, continuous targets' observation time is extended beyond that of a single chirp duration...journal article 2019

Bidon, Stéphanie (author), Lasserre, Marie (author), le Chevalier, F. (author)The problem considered is that of estimating unambiguously migrating targets observed with a wideband radar. We extend a previously described sparse Bayesian algorithm to the presence of diffuse clutter and off-grid targets. A hybrid-Gibbs sampler is formulated to jointly estimate the sparse target amplitude vector, the grid mismatch, and the...journal article 2019

Petrov, N. (author), le Chevalier, F. (author), Yarovoy, Alexander (author)This paper deals with the problem of coherent radar detection of fast moving targets in a high range resolution mode. In particular, we are focusing on the spiky clutter modeled as a compound Gaussian process with rapidly varying power along range. Additionally, a fast moving target of interest has a few range cells migration within the coherent...journal article 2018
