Abstract: A new method is presented for Doppler spectral averaging that more reliably identifies the profiler radar return from clear air in the presence of contamination?for example, from migrating bird echoes. These very sensitive ...

Abstract: Under normal operating conditions, engine crankshaft bearings experience variations in oil film temperature due to shearing of the oil film. This can have a negative impact on the bearing operating life since the viscosity ...

Abstract: adar wind profiler (RWP) systems observe radar returns from refractive index fluctuations due to clear-air turbulence. The Doppler spectra used to compute the moments of the returned signal always include noise from various ...

Abstract: he DeTect Inc. RAPTOR velocity?azimuth display boundary layer (VAD-BL) radar wind profiler is a pulsed Doppler radar used to make automatic unattended measurements of wind profiles in the lower atmosphere. All data products ...

Abstract: Radar wind profilers (RWPs) sense the mean and turbulent motion of the clear air through Doppler shifts induced along several (3?5) upward-looking beams. RWP signals, like all radars signals, are often contaminated. The ...

Abstract: The System Demonstration and Integration Division of the Environmental Technology Laboratory and the Battlefield Environment Directorate of the U.S. Army Research Laboratory have designed and built the Mobile Profiler ...
