Optimization of the NRCS Sampling at the Sea Wind Retrieval by the Airborne Rotating-Beam Scatterometer Mounted under Fuselage [PDF]
Sensors, 2022 The optimization of normalized radar cross-section (NRCS) sampling by a scatterometer allows an increase in the accuracy of the wind retrieval over the water surface and a decrease in the time of the measurement.

A More Accurate Field-to-Field Method towards the Wind Retrieval of HY-2B Scatterometer
Remote Sensing, 2021 In this paper, we present a method for retrieving sea surface wind field (SSWF) from HaiYang-2B (HY-2B) scatterometer data. In contrast to the conventional algorithm, i.e., using a point-to-point (P2P) method based on geophysical model functions (GMF) to

A Novel Integrated Algorithm for Wind Vector Retrieval from Conically Scanning Scatterometers
Remote Sensing, 2013 Due to the lower efficiency and the larger wind direction error of traditional algorithms, a novel integrated wind retrieval algorithm is proposed for conically scanning scatterometers. The proposed algorithm has the dual advantages of less computational

A generalized simulation capability for rotating- beam scatterometers [PDF]
Atmospheric Measurement Techniques, 2019 Rotating-beam wind scatterometers exist in two types: rotating fan-beam and rotating pencil-beam. In our study, a generic simulation frame is established and verified to assess the wind retrieval skill of the three different scatterometers: SCAT on ...
