Calibration of the Normalized Radar Cross Section for Sentinel-1 Wave Mode [PDF]

open access: yesIEEE Transactions on Geoscience and Remote Sensing, 2019
Sentinel-1 (S-1) is a two-satellite constellation for continuity of operational synthetic aperture radar (SAR) observations. Wave mode (WV) is the default mode over open ocean for S-1 to monitor global ocean waves and wind field. Therefore, proper radiometric calibration is essential to accurately infer these geophysical quantities. Based on the global

Geochemical analysis of SAR backscattering (Sentinel-1) on global ocean oil spill cases

open access: yesEuropean Journal of Remote Sensing, 2023
The oil spill is one of the most impactful sources of marine pollution on the ocean surface, detected by the SAR sensors as dark areas, regions with low backscatter values. Due to the complex mixture of hydrophobic hydrocarbons, mineral oil spills change

Impact of emulsification of crude oil on normalized radar cross section [PDF]

open access: yesJournal of Oceanology and Limnology, 2019
The emulsification of crude oil is caused by the oil flowing into the water, resulting in the increase of oil film tension, viscosity, water content, and volume, which brings great harm to the marine ecological environment and difficulties for the cleanup of marine emergency equipment.

94 GHz Radar Backscatter Characteristics of Alpine Glacier Ice

open access: yesGeophysical Research Letters, 2023
Measuring the radar backscatter characteristics of glacier ice at different frequencies and incidence angles is fundamental to predicting the glacier mapping performance of a sensor. However, such measurements at 94 GHz do not exist.

On the joint use of scattering and damping models to predict X-band co-polarized backscattering from a slick-covered sea surface

open access: yesFrontiers in Marine Science, 2022
In this study, sea surface scattering with and without surfactants is predicted using the two-scale boundary perturbation model (BPM) and the advanced integral equation model (AIEM) augmented with two different damping models, i.e., the Marangoni one and
