Simulations of sea surface reflection for V-band O2 differential absorption radar barometry

Frontiers in Remote Sensing, 2023
This study simulates V-band sea surface reflectance and normalized radar cross-section (NRCS) for sea surface air pressure barometry using a differential absorption radar operating at three spectrally even spaced close frequency bands (65.5, 67.75 and 70.

Incidence angle normalization of Wide Swath SAR data for oceanographic applications

Open Geosciences, 2016
A backscattering trend in the range direction of the signal received by Synthetic Aperture Radar (SAR) in Wide Swath (WS) mode results in a progressive reduction of brightness over images from near to far range, which affects the detection and ...

Development of a New Tropical Cyclone Strip Segment Retrieval Model for C-Band Cross-Polarized SAR Data

Remote Sensing, 2022
Compared with co-polarized (HH/VV) normalized radar cross-section (NRCS) backscattered from the sea surface, there is no saturation phenomenon in cross-polarized (HV/VH) NRCS when wind speed is greater than about 20 m/s, so cross-polarized synthetic ...

Technical Evaluation of Sentinel-1 IW Mode Cross-Pol Radar Backscattering from the Ocean Surface in Moderate Wind Condition

Remote Sensing, 2017
The Sentinel-1 synthetic aperture radar (SAR) allows sufficient resources for cross-pol wind speed retrievals over the ocean. In this paper, we present technical evaluation on wind retrieval from both Sentinel-1A and Sentinel-1B IW cross-pol images ...

Sea Ice Concentration Manifestation in Radar Signal at Low Incidence Angles Depending on Wind Speed

Remote Sensing
In previous studies, the possibilities of Ku-band radar measurements at low incidence angles were investigated for the task of sea ice detection. In this paper, the sensitivity of normalized radar cross-section to sea ice concentration is investigated at
