LOW-COST, SOFTWARE DEFINED FMCW RADAR FOR OBSERVATIONS OF DRONES
(2017-05-12)
This thesis focuses on implementing a small, low-cost, Frequency-Modulated-Continuous-Wave (FMCW) radar sensor using Software-Defined Radio (SDR) platforms. Extensive investigation and comparisons of existing SDRs are ...
A LAGRANGIAN PERSPECTIVE OF MESOCYCLONES AND DOWNDRAFTS IN OBSERVED AND NUMERICALLY SIMULATED SUPERCELLS
(2018-05)
On 29 May 2004, a high-precipitation supercell thunderstorm developed in western Oklahoma and produced tornadoes during almost every distinct mesocyclone cycle over a six-hour period. The storm was exceptional in its size, ...
Simulation and Adaptive Aperture Allocation for All-Digital Phased-Array Radar
(2019-08-01)
Increased flexibility afforded by all-digital radar architectures and operational concepts such as MIMO radar can be leveraged with new waveforms and aperture allocation methods to improve radar performance in diverse ...
An Evaluation of Radar- and Satellite-Data Based Products to Discriminate Between Tornadic and Non-Tornadic Storms
(2017-12)
Severe weather, and specifically tornadoes, can pose a significant threat to property and human life. Tornadic storms have been extensively studied using radar observations for decades, and some more recent studies have ...
A NEW RESEARCH METHOD TO EVALUATE THE IMPACT OF WET RADOMES ON DUAL-POLARIZED WEATHER RADARS AND COMMUNICATION SYSTEMS
(2018-12-14)
The purpose of this dissertation is to provide a detailed study of the effect of water accumulated on wet radomes. To accomplish this goal, a novel method to evaluate the impact of wet radomes on dual-polarized weather ...
An Investigation and Solution to Spatial Interferers Before RF Front End for Phased Arrays
(2019-05-10)
Fully digital arrays offer significant advantages in terms of flexibility and performance, however they suffer from dynamic range issues when used in the presence of in-band interferers. Higher dynamic range components may ...
The Use of Polarimetric Radar Data for Informing Numerical Weather Prediction Models
(2018-05-11)
The explicit prediction of convective storms using storm-scale models has recently become a reality. Radar data is a crucial source of information about the microphysical and kinematic properties of convection at the ...
