Velocity Azimuth Display A radar display on which mean radial velocity is plotted as a function of azimuth See VWP
(Velocity Azimuth Display) a radar display on which the mean radial velocity is plotted as a function of azimuth
Vacuum Arc Discharge Fowler-Nordheim region of the Volt-Ampere curve where auto-electronic emission becomes continuous (field-emission)
The VAD (Velocity Azimuth Display) technique is used to retrieve the vertical wind profile at the radar site with a Doppler radar PPI scans at an elevation of about 20° cover various heights with one scan
voice activity detection When enabled on a voice port or a dial peer, silence is not transmitted over the network, only audible speech When VAD is enabled, the sound quality is slightly degraded but the connection monopolizes much less bandwidth
Velocity-Azimuth Display; algorithm to display the horizontal wind-vector calculated from the radial wind speed measured at high elevation (34 and 40 degree), as a function of azimuth and assuming horizontal homogeneity
