Abstract: A Doppler radar operating at 3.2 mm wavelength was designed and assembled primarily for observation of clouds and precipitation. Phase detection of the radar signals which is required for Doppler operation is implemented ...

Abstract: This article is concerned with investigations of scattering and absorption of 35, 94, 140, and 240 GHz radiation by clouds and precipitation. The computations of radar reflectivity, Doppler spectra, and absorption coefficients ...

Abstract: The paper discusses the use of airborne pulse-Doppler techniques for the sensing of particle motion inside convective storms. A downward-looking beam method providing observations of particle vertical velocity distributed ...

Abstract: In this paper we present and discuss techniques for the computation of the mean and spectral variance of a pulse-to-pulse coherent sonar signal, leading to the measurement of mean water velocity and turbulence. The use of ...

Abstract: A Doppler radar has been used in central Oklahoma to probe the motion of invisible targets usually referred to as ?angels.? The large density targets detected on certain days suggests the presence of a dense atmospheric ...

Abstract: This paper presents dual-Doppler radar observations and analysis of the kinematics of a convective storm which developed under sea breeze conditions over the area of Miami, Fla. The method, which is based on simultaneous ...

Abstract: Doppler wind soundings were taken in the lower 4.5 km of the atmosphere at 12 minute intervals during a seven hour period in a snowstorm over eastern Massachusetts. A time-height cross section of the wind revealed numerous ...
