Abstract

Modern, multifunctional ground-based weather radar systems deployed at the airports are designed to detect and track point-like targets, such as birds and drones. Therefore, these radars scan the field of view in azimuth very fast to get quick updates on the whereabouts of these targets. The fast scanning nature of these radars limits their capacity to accurately estimate parameters for weather applications, such as the precipitation intensity and velocity distribution parameters of the raindrops during rainy conditions. This thesis aims to develop novel techniques to estimate the parameters related to the precipitation Doppler spectrum with limited time on target. In addition to estimating the parameters, this thesis extensively discusses the trade-offs and recommends
application-specific measurement techniques....
