Doppler radar spectral width broadening due to beamwidth and wind shear
The spectral width observed by Doppler radars can be due to several eects including the atmospheric turbulence within the radar sample volume plus eects associated with the background ̄ow and the radar geometry and con®guration. This study re-examines simple models for the eects due to ®nite beamwidth and vertical shear of the horizontal wind. Analytic solutions of 1and 2-dimensional models ...
متن کامل8.1 Development of a Climatology of Vertically Complete Wind Profiles from Doppler Radar Wind Profiler Systems
Space vehicle loads and trajectory assessments utilize archives of both discrete and sequential wind profiles to ensure robust structural integrity during vehicle design. Historically, vehicle programs have used balloonbased measurements, which have three primary limitations inherent to balloon systems. First, the high cost of balloon releases makes high-frequency balloon sampling impractical, ...

this experimental study has been conducted to test the effect of oral presentation on the development of l2 learners grammar. but this oral presentation is not merely a deductive instruction of grammatical points, in this presentation two hypotheses of krashen (input and low filter hypotheses), stevicks viewpoints on grammar explanation and correction and widdowsons opinion on limited use of l1...
15 صفحه اولNonparametric estimation of mean Doppler and spectral width
This paper proposes a new nonparametric method for estimation of spectral moments of a zero-mean Gaussian process immersed in additive white Gaussian noise. Although the technique is valid for any order moment, particular attention is given to the mean Doppler (first moment) and to the spectral width (square root of the centered second-spectral moment). By assuming that the power spectral densi...
