Kumbul, U. (author)Autonomous driving is a new emerging technology that will enhance traffic safety. Automotive radars are essential to attaining autonomous driving since they can function in adverse weather conditions and are used for detection, tracking, and classification in traffic settings. However, the dramatic growth in the number of radar sensors used for...doctoral thesis 2023

Wang, J. (author), Ding, M. (author), Yarovoy, Alexander (author)A novel matrix-pencil (MP)-based interference mitigation approach for frequency-modulated continuous-wave (FMCW) radars is proposed in this article. The interference-contaminated segment of the beat signal is first cut out, and then, the signal samples in the cutout region are reconstructed by modeling the beat signal as a sum of complex...journal article 2021

Reinoso Rondinel, R. (author), Schleiss, M.A. (author)Conventionally, Micro Rain Radars (MRRs) have been used as a tool to calibrate reflectivity from weather radars, estimate the relation between rainfall rate and reflectivity, and study microphysical processes in precipitation. However, limited attention has been given to the reliability of the retrieved drop size distributions (DSDs) from...journal article 2021

Ritchie, M. (author), Capraru, R. (author), Fioranelli, F. (author)Radar sensors have a new growing application area of dynamic hand gesture recognition. Traditionally radar systems are considered to be very large, complex and focused on detecting targets at long ranges. With modern electronics and signal processing it is now possible to create small compact RF sensors that can sense subtle movements over...journal article 2020

Jin, J. (author), Duan, Yunling (author)Surrounding rock quality of underground caverns is crucial to structural safety and stability in geological engineering. Classic measures for rock quality investigation are destructive and time consuming, and therefore technology evolution for efficiently evaluating rock quality is significantly required. In this paper, the non-destructive...journal article 2020

Dogan, O. (author), Uysal, Faruk (author), Lopez Dekker, F.J. (author)A wide-swath synthetic aperture radar (SAR) image is known to be achievable by merging multistatic aliased data that is collected with an appropriate along-track displacement. However, in terms of both flexibility requirements like potentiality of both along-track and cross-track (XT) interferometry and design requirements like orbital safety,...journal article 2020

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

Reinoso Rondinel, R. (author)Observations of weather phenomena have attracted many researchers because of their microphysical complexity, space-time variability, and more important, their impact on human life. In the efforts of studying weather, researchers have used a diverse number of instruments to obtain both in-situ (towers, tethered balloons, and weather station...doctoral thesis 2018

Reinoso Rondinel, R. (author), Unal, C.M.H. (author), Russchenberg, H.W.J. (author)One of the most beneficial polarimetric variables may be the specific differential phase K<sub>DP</sub> because of its independence from power attenuation and radar miscalibration. However, conventional K<sub>DP</sub> estimation requires a substantial amount of range smoothing as a result of the noisy characteristic of the measured...journal article 2018

Wangkheimayum, Kajengkhombi (author), Krasnov, O.A. (author), Yarovoy, Alexander (author)A simplified polarimetric model for radar signal scattering on wind turbines (WT) is proposed, which can be used for interpretation of observation in time and Doppler domains. This model uses representation of real WT as slowly rotating linear wire structures. The earlier proposed model has been extended to more general cases of WT with...conference paper 2018
