Scattering experiments from breaking gravity waves conducted at a wave tank facility at small grazing angles in the absence of wind are analyzed. Breaking gravity waves are studied using a fully plane polarimetric horizontal (HH), vertical (VV), vert

Results of X-band microwave backscatter from sea surfaces at a small-grazing angle for a range of wind speeds (3.8-10.3 m/s) are presented. The data indicate that the speed of faster-than-Bragg scatterers and their time-averaged polarization ratio bo

A quiescent plasma is sustained for 80 energy confinement times by only gas fuelling and neutral beam heating in an axisymmetric region of the Tandem Mirror Experiment Upgrade (TMX-U). This plasma should be unstable because of the bad magnetic curvat

Observations of microwave backscattering from the sea surface have indicated the presence of scattering mechanisms other than Bragg resonant mechanisms. These conclusions are supported by the study of the line shapes of Doppler spectra and of the dep

Breaking gravity waves are studied in a wave tank at small grazing angles (4.5/spl deg/-11/spl deg/) where all four polarization elements (HH, VV, HV, VH) are simultaneously measured. Temporally averaged Doppler spectra are obtained for mechanically-

Experiments on grazing angle, polarization and wind-direction dependent microwave backscatter from ocean surfaces are reviewed. A direct proof that non-Bragg and fast scatterers are also required to account for microwave returns has been made through

In recent applications using an optical specular even detector (OSED I), a plane-polarimetric active-imaging system, results have shown that water surfaces supporting breaking gravity waves are efficient depolarizing scatterers at both microwave and

In this paper, we describe TRW's latest version of the scanning laser slope gauge (SLSG) which was used to characterize the sea surface in a recent ocean experiment. The SLSG, capable of measuring the spatial distribution and temporal evolution of th
