Gale Wind Speed Retrieval Algorithm Using Ku-Band Radar Data Onboard GPM Satellite
An algorithm to retrieve the wind speed within a wide swath from the normalized radar cross section (NRCS) is developed for the data of Ku-band radar operating in scanning mode installed onboard the Global Precipitation Measurement (GPM) satellite.

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