Bosma, Detmer (author), Krasnov, O.A. (author), Yarovoy, Alexander (author)A dedicated signal and data processing chain is proposed for a fully polarimetric Doppler surveillance S-band radar to extract the polarimetric signatures of moving targets. To extract the target’s polarimetric features, detection, clustering, and tracking steps are realized for a multi-target environment in the range-Doppler domain. A dedicated...journal article 2023

Gong, Huaiyang (author), Petrov, N. (author), Krasnov, O.A. (author), Yarovoy, Alexander (author)This paper presents algorithms for joint signal processing of data from two radars located on the rooftop of TU Delft: PARSAX, operating in S-band, and MESEWI, operating in X-band [1]. In particular, the problem of data alignment in space (2D map) and time is addressed by observing moving targets of opportunity in the high-resolution mode. After...conference paper 2022

Petrov, N. (author), Yiğit, Erkut (author), Krasnov, O.A. (author), Yarovoy, Alexander (author)The paper presents the statistical analysis of trihedral corner reflectors RCS in presence of mass production and installation errors. It is shown that the degradation of RCS from its nominal value can be modeled by Beta distribution. The derived probability density functions (PDF) of corner reflector RCS is further exploited to design an...conference paper 2022

Petrov, N. (author), Krasnov, O.A. (author), Yarovoy, Alexander (author)This paper presents an analysis of a new method of automotive radar self-calibration which uses targets of opportunity. While conventional offline calibration of a phased array antenna requires accurate knowledge of the positions of calibration targets relative to the radar, such information is not available in a dynamic scenario. To...journal article 2021

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

Petrov, N. (author), Krasnov, O.A. (author), Yarovoy, Alexander (author)In this paper, the problem of on-the-fly estimation of the radar state (self-diagnostics) is considered. We propose to use repetitive objects of the road infrastructure, such as lampposts, for continuous diagnostics of the radar state. The selected approach allows accounting for the external factors, such as water layer or...conference paper 2019

Kladogenis, Chrysovalantis (author), Driessen, J.N. (author), Krasnov, O.A. (author), Yarovoy, Alexander (author)Wind turbines usually cause significant interference in the conventional radar operations which might degrade the detection capabilities. Wind turbines do not only block the radar beam focusing on a specific target, thus creating shadowing effects, but also impose Doppler spectra contamination due to the continuous blade rotation. Therefore...conference paper 2019
