How Does Wind Influence Near-Nadir and Low-Incidence Ka-Band Radar Backscatter and Coherence from Small Inland Water Bodies?

open access: yesRemote Sensing, 2023
While many studies have been conducted regarding wind-driven Ka-band scattering on the ocean and sea surfaces, few have identified the impacts of Ka-band scattering on small inland water bodies, and fewer have identified the influence of wind on ...

Speckle Noise Spectrum at Near-Nadir Incidence Angles for a Time-Varying Sea Surface [PDF]

open access: yesIEEE Transactions on Geoscience and Remote Sensing, 2022
Speckle noise is inherent to radar measurements. For applications which need both a high temporal and high spatial resolution, a classical method for the reduction of the speckle noise by filtering the backscattered signal may not be sufficient. In particular, when radar observations are used to estimate ocean wave spectra from relative fluctuations of

Analysis of Dual-Frequency Ocean Backscatter Measurements at Ku- and Ka-Bands Using Near-Nadir Incidence GPM Radar Data [PDF]

open access: yesIEEE Geoscience and Remote Sensing Letters, 2016
Global colocalized ocean surface measurements using the Global Precipitation Measurement near-nadir dual-frequency Ku- and Ka-band microwave measurements are analyzed and compared. Focusing on the Ka and Ku cross-sections fall-off with incidence angles, the contemporaneous measurements enable to more precisely document differing ocean scattering ...

Impact of Intraoperative Nanocarbon Staining and parathyroid autotransplantation on parathyroid injury and recovery in adult thyroidectomy: a retrospective cohort study [PDF]

open access: yesBMC Surgery
Background Thyroid surgeries are intricate operations that carry the risk of damaging the parathyroid glands, which can result in hypocalcemia and potential long-term hypoparathyroidism.
