Calculating wind profile from Doppler spectra of lower-atmosphere observation radar

摘要

Abstract: This paper presents an algorithm for calculating windprofiles form profiler Doppler spectra. Our algorithmproduces hourly averaged winds by consensus averagingof the spectral peak power densities. The peak powermethod, applied separately on each height and on eachantenna beam, can detect the atmospheric echo in eachspectrum which results in the calculation of radialvelocities in all antenna beams. The consensusalgorithm is then applied to average over one-hourintervals using 12 radial velocities over each hour. Aresultant 24-hour profile of horizontal winds is givento illustrate the effectiveness of the algorithm. !4
