Retrieval of single-Doppler radar wind field by nonlinear approximation

Advances in Atmospheric Sciences, 2003
The methods employed in recent years to retrieve vector wind information from single-Doppler radar observation are reviewed briefly. These methods are based on a linearity hypothesis for the wind field, so the retrieved wind field is sometimes negatively affected by the non-linearity of wind.

Coastal wind field retrievals from ERS SAR images

IGARSS'97. 1997 IEEE International Geoscience and Remote Sensing Symposium Proceedings. Remote Sensing - A Scientific Vision for Sustainable Development, 2002
A unique series of ERS-1/2 C-band SAR images was obtained off the southern coast of Norway during the COAST WATCH'95 experiment in September 1995. In this paper the authors carry out a systematic analysis of the mesoscale coastal wind field conditions expressed in the SAR images. Four different categories of phenomena including wind rows, fetch limited

First Russian scatteromer: Numerical simulation of wind field retrieval

2015 Radio and Antenna Days of the Indian Ocean (RADIO), 2015
This study continues our previous explorations of the new space-borne scatterometer concept. Using a fan-beam antenna and simultaneous RCS measurements at the horizontal and vertical polarizations, one can improve the accuracy of wind speed and wind direction retrieval.

3D wind field retrieval from spaceborne Doppler radar

SPIE Proceedings, 2012
Numerous space missions carrying a radar are presently envisioned, particularly to study tropical rain systems. Among those missions, BOITATA is a joint effort between Brazil (INPE/AEB) and France (CNES). The goal is to embark a Doppler radar with scanning possibilities onboard a low-orbiting satellite.

Wind field retrieval from SAR images using the continuous wavelet transform

IEEE International Geoscience and Remote Sensing Symposium, 2003
The paper describes the results of a method, based on the two dimensional wavelet technique, to retrieve the wind field from Synthetic Aperture Radar (SAR) images without any external information about the wind direction. This method works well when backscatter structures formed by wind rolls are evidenced by SAR images.
