Abstract
Jicamarca radar located in Peru is used to probe the equatorial mesosphere by scattering 50 MHz pulse transmissions from mesospheric turbulent layers; the pulse returns are detected by the radar antenna and subsequently spectral analyzed. This thesis describes the Jicamarca radar con figuration used for mesospheric Doppler wind measurements as well as the data processing procedure used to obtain wind estimates from spectral data. The procedure was initially developed by Sheth et al. [2006] and improved by Smith [2014], but it still gave biased wind estimates when the sidelobe power levels exceeded the mainlobe power detected by the antenna beams used in the measurements. We describe a clustering-based method developed to detect and remove the sidelobe components of the return signals to obtain bias-free wind estimates.
