TL;DR: A van-mounted, pulsed doppler (10GHz) radar collected surface-velocity data across the Skagit River, Washington at a USGS streamgaging station using Bragg scattering from short waves produced by turbulent boils on the surface of the river as discussed by the authors.
Journal ArticleDOI
Evidence of Bragg scattering in microwave Doppler spectra of sea return
TL;DR: In this article, a model of microwave Doppler spectra based on Bragg-scattering, composite-surface theory is developed and used to show that the results obtained in these field studies are compatible with the hypothesis that Bragg scattering dominates microwave backscatter from rough water surfaces under many wind speed and incidence angle conditions.
Journal ArticleDOI
The dependence of X band microwave sea return on atmospheric stability and sea state
TL;DR: In this article, the dependence of microwave sea retun at an incidence angle in the Bragg regime on wind speed, atmospheric stability, dominant wave slope, and dominant wave frequency has been measured.
Journal ArticleDOI
Parametric dependence of ocean wave-radar modulation transfer functions
TL;DR: In this paper, the dependence of ocean-wave radar modulation transfer functions (MTFs) on various environmental and radar parameters during the Marine Remote Sensing experiment of 1979 (MARSEN 79).
Journal ArticleDOI
Ocean wave-radar modulation transfer functions from the West Coast Experiment
TL;DR: In this article, the authors measured the modulation transfer functions (the ratio of the cross spectrum of the line-of-sight orbital speed and backscattered microwave power to the autospectrum of the LOS orbital speed) at 9.375 and 1.5 GHz (Bragg wavelengths of 2.3 and 13 cm) for winds up to 10 m/s and ocean wave periods from 2-18 s.
