DOI: 10.1109/lgrs.2020.3009304
Abstract: Modern radar systems use square-law detectors to search and track fluctuating targets embedded in Weibull-distributed ground clutter. However, the theoretical performance analysis of square-law detectors in the presence of Weibull clutter leads to cumbersome mathematical… read more here.

DOI: 10.1109/tgrs.2020.3044111
Abstract: This article proposes a method for estimating the Doppler power spectrum (DPS) of a weather radar via minimum mean square error (MMSE). In order to detect severe weather phenomena that mostly occur within the lowest… read more here.

DOI: 10.1109/tgrs.2022.3223386
Abstract: An empirical mode decomposition (EMD)-based intermittent and ground clutter removal algorithm for radar windprofilers is proposed. Intrinsic mode functions (IMFs) affected with intermittent clutter are identified and are separated into amplitude-modulated (AM) and frequency-modulated (FM)… read more here.

DOI: 10.1175/jtech-d-16-0072.1
Abstract: AbstractThe staggered–pulse repetition time (SPRT) technique has been shown to be effective at mitigating range and velocity ambiguities; however, mitigation of ground clutter contamination for SPRT sequences has proven to be more challenging. Using the… read more here.

DOI: 10.5194/amt-16-1789-2023
Abstract: Abstract. Radio waves propagating in the atmosphere are affected by the prevailing atmospheric state. The state of the atmosphere can cause radio waves to refract more or less towards the ground. When the refractive index… read more here.
