Data Processing and Airborne Experiment Results Analysis of a Fully Polarized Scatterometer

2013 IEEE International Geoscience and Remote Sensing Symposium - IGARSS, 2013
Scatterometers are key instruments for remotely sensing of ocean surface winds. The Ku-band airborne full polarized scatterometer (AFPSCAT) of the Airborne Remote Sensing System (ARSS) was developed mainly for this application by the Key Laboratory of Microwave Remote Sensing in National Space Science Center of Chinese Academy of Sciences. Its rotating

Ocean remote sensing with airborne K/sub u/-band scatterometer

Proceedings of OCEANS '93, 2002
An airborne K/sub u/-band scatterometer (NUSCAT) was used to measure ocean backscatter during the Surface Wave Dynamics Experiment (SWADE). The objective is to improve understanding of the relationship between ocean radar backscatter and near surface winds.

Airborne scatterometers: investigating ocean backscatter under low- and high-wind conditions

Proceedings of the IEEE, 1994
Attempting to understand and predict weather on a local and global basis has challenged both the scientific and engineering communities. One key parameter in understanding the weather is the ocean surface wind vector because of its role in the energy exchange at the air-sea surface. scatterometers, radars that measure the reflectivity of a target offer

Hurricane Wind Retrieval Algorithm Development for a Conical Scanning Airborne Scatterometer

Proceedings of the IEEE SoutheastCon 2006, 2006
This paper presents the description of a data processing algorithm to provide near real-time wind retrievals (wind speed and direction) for hurricanes. This procedure uses conically scanning airborne microwave scatterometer measurements of ocean surface backscatter to infer the surface wind parameters.

An Airborne C-band Scatterometer For Remote Sensing The Air-sea Interface

12th Canadian Symposium on Remote Sensing Geoscience and Remote Sensing Symposium,, 2005
An airborne C-band scatterometer system (C-Scat) has been developed for remote sensing of the air-sea interface. The sensor has been designed to fly on a number of research aircraft, beginning with the NASA Ames Research Center's C-130B, on which test flights were conducted in August of 1988.

Attenuation Correction over Ocean for the HIWRAP Dual-Frequency Airborne Scatterometer

Journal of Atmospheric and Oceanic Technology, 2019
Abstract An important objective in scatterometry is the estimation of near-surface wind speed and direction in the presence of rain. We investigate an attenuation correction method using data from the High-Altitude Imaging Wind and Rain Airborne Profiler (HIWRAP) dual-frequency scatterometer, which operates at Ku ...
