Wind Direction Extraction from SAR in Coastal Areas

This paper aims to illustrate and test a method, based on the Two-Dimensional Continuous Wavelet Transform (2D-CWT), developed to extract the wind directions from the Synthetic Aperture Radar (SAR) images. The knowledge of the wind direction is essential to retrieve the wind speed by using the radar-backscatter versus wind speed algorithms. The method has been applied to 61 SAR images from diff...

Wind Direction Extraction from Coastal SAR Images Using Cross-spectral Method

A sensitive processing method for extracting the wind direction from SAR (synthetic aperture radar) images is presented. We transfer SAR images to the image spectra using two-dimensional FFT (fast Fourier transform) and take the integral of the image spectra between the wave length 400 m and 800 m, which is high end containing wind direction signatures in Lband SAR. From this and a reference si...

Models for Features Extraction from Sar Images of Urban Areas

Features extraction from SAR images of urban scenes represents one of the most interesting subjects of research in the field of remote sensing; new, more adequate and specialised backscattering and radar models for features retrieval are studied and strongly required. In this paper, a synoptic view of three different approaches to the problem, accounting for the dynamism and complexity of urban...

Pollutant transport in coastal areas with and without background wind

A three-dimensional meteorological model and a Lagrangian particle dispersion model are used to study the e€ects of a uniform large-scale wind on the dispersion of a non-reactive pollutant in a coastal region with complex terrain. Simulations are carried out both with and without a background wind. A comparison between model results and measured data (wind and pollutant concentrations) indicate...

An Improved Local Gradient Method for Sea Surface Wind Direction Retrieval from SAR Imagery

Sea surface wind affects the fluxes of energy, mass and momentum between the atmosphere and ocean, and therefore regional and global weather and climate. With various satellite microwave sensors, sea surface wind can be measured with large spatial coverage in almost all-weather conditions, day or night. Like any other remote sensing measurements, sea surface wind measurement is also indirect. T...
