Dash, T.K. (author), Driessen, J.N. (author), Krasnov, O.A. (author), Yarovoy, Alexander (author)The problem of the limited accuracy of precipitation Doppler spectrum moments estimation measured by fast azimuthally scanning weather radars is addressed. A novel approach for the Doppler moment estimation based on maximum likelihood estimation is proposed. A simplified semianalytical parametric model for the precipitation power spectral...journal article 2024

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

Oude Nijhuis, A.C.P. (author), Unal, C.M.H. (author), Krasnov, O.A. (author), Russchenberg, H.W.J. (author), Yarovoy, Alexander (author)In this article, five velocity-based energy dissipation rate (EDR) retrieval techniques are assessed. The EDR retrieval techniques are applied to Doppler measurements from Transportable Atmospheric Radar (TARA)—a precipitation profiling radar—operating in the vertically fixed-pointing mode. A generalized formula for the Kolmogorov constant is...journal article 2019

Wang, Z. (author), Krasnov, O.A. (author), Babur, G.P. (author), Ligthart, L.P. (author), Van der Zwan, F. (author)This paper presents the development of a reconfigurable receiver to undertake challenging signal processing tasks for a novel polarimetric radar system. The field-programmable gate arrays (FPGAs)-based digital receiver samples incoming signals at intermediate frequency (IF) and processes signals digitally instead of using conventional analog...journal article 2011
