In this letter, a new method for estimating wind speeds from X-band nautical radar images is presented. Wind speeds are determined from the wavenumber spectra of radar backscatter using a logarithmic relationship between the spectral strength and the wind speed. The method can be applied to both rain-contaminated and rain-free radar data. The method has been tested using shipborne X-band nautical...
In this paper, a new method for retrieving wind speeds from rain-contaminated X-band nautical radar images is presented. The method mitigates rain influence by applying the gamma correction to rain-contaminated images, and then relates the average intensities of radar images to the measured wind speeds with a logarithmic function. The method has been tested using X-band nautical radar images and shipborne...
In this paper, an algorithm for retrieving wind direction from rain-contaminated radar images collected under low wind speed conditions is presented. The algorithm investigates radar backscatter in the wavenumber domain and determines wind directions based on spectral components with wavenumbers of [0.01, 0.2]. The algorithm has been tested using rain-contaminated X-band marine radar images and shipborne...
