This paper presents a novel sensor for the detection and characterization of regions of air turbulence. As part of the ground truth process, it consists of a combined Schlieren imager and a Radar Acoustic Sounding System (RASS) to produce dual-modali

A method of detecting atmospheric ducts using a wind profiler radar (WPR) and a radio acoustic sounding system (RASS) is proposed. The method uses the RASS to measure the virtual temperature profile and calculate the Brunt–Väisälä frequency; it

Thermodynamic profiles are often retrieved from the multi-wavelength brightness temperature observations made by microwave radiometers (MWRs) using regression methods (linear, quadratic approaches), artificial intelligence (neural networks), or physi

On June 28, 1996, RASS (radio-acoustic sounding system) and aircraft observations were taken of the evolving boundary layer as part of the Montreal experiment on regional mixing and ozone (MERMOZ). The vertical air velocity measurements of the RASS w

Economic Technology for Atmosphere Parameters Distant Recording Using Radio Acoustic Sounding System
Publikováno v:

A new technology for RASS – a passive radar sensing of the scattered signals spot focused on the underlying surface by spherical wave fronts of an acoustic package – is considered. An original way of distant recording of wind vertical profiles an

Radio sounding systems are perspective candidates for use as remote wind sensors for wind turbine. An obstacle to their use is the need, on the one hand, to provide direct contact of the acoustic emitter with the external environment, and on the othe

The 915 MHz radar wind profiler/radio acoustic sounding system (RWP/RASS) measures wind profiles and backscattered signal strength between (nominally) 0.1 km and 5 km and virtual temperature profiles between 0.1 km and 2.5 km. It operates by transmit
