Assessing scanning strategies with all-digital phased array weather radars for characterization and detection of microbursts
Pearson, Connor (2022-05-13)Microbursts are a rapidly evolving, vertically oriented meteorological phenomena that can be extremely hazardous to aviation, and other human activities, if left undetected. The temporal resolution and vertical sampling ... -
The Bootstrap Dual Polarimetric Spectral Density Estimator
Umeyama Matsumoto, Arturo Yoshiyuki (2016-08)Weather radar moments and polarimetric variables provide useful information about the characteristics and motion of hydrometeors. However, the bulk information may be masked when the meteorological signal of interest is ... -
Fast Adaptive Digital Beamforming With Machine Learning
Kim, Yoon-SL (2022-12-16)Digital polarimetric Phased Array Radar (PAR) has the potential to achieve high temporal and spatial resolution needed for next-generation weather observations. It offers flexibility in scanning strategies, including the ... -
A fuzzy logic algorithm for classifying bird and insect radar echoes at S-band
Jatau, Precious (2018-08-02)A fuzzy logic algorithm for the separation of bird echoes from insect echoes using Next Generation Radar (NEXRAD) and considering range effects has been developed. The radar used in this study is the S-band (10 cm wavelength) ... -
MULTIPLE HYPOTHESIS TRACKING AND STRONG POINT ANALYSIS FOR STORM TRACKING WITH WEATHER RADAR
Judy, Matthew (2020-05-08)Storm tracking using radar observations of weather is a valuable tool both for the study of weather conditions and for the issuance of advance warning when such conditions are severe. Centroid-based storm tracking algorithms ... -
Observations of Cold Front Features at High Spatiotemporal Resolution Using the Atmospheric Imaging Radar
Mahre, William Andrew (2016-08-12)Over the past 40+ years, cold front vertical structure has been studied for the purpose of increased understanding of convection initiation and aviation safety. Traditional scanning radars tend to not be well-suited for ... -
Reverse Backprojection Method for Simulation of Passive Bistatic SAR Data
Brumble, Tayler (2017-12-15)Synthetic Aperture Radar (SAR) is a valuable tool for acquiring information about landscapes through forming two-dimensional images remotely. SAR has useful applications for defense, intelligence, humanitarian, and urban ... -
Simulation of Polarimetric Phased Array Weather Radars
Byrd, Andrew (2016-05)Polarimetric phased array radars (PPARs) are a rapidly developing area of research interest in weather radar. However, they present intrinsic challenges for calibration and operation. Foremost among these are the adverse ... -
Spatially-Temporally Resolved Sampling System for Carbon Dioxide Concentration in The Atmospheric Boundary Layer: A Low-Cost UAS Approach
Britto Hupsel de Azevedo, Gustavo (2020-05-08)Given the consensus around the importance of atmospheric carbon dioxide (CO2) to human life on earth, its monitoring has grown significantly in the past 60 years. However, there is still a knowledge gap regarding the ... -
A STATE VECTOR AUGMENTATION METHOD FOR INCLUDING VELOCITY INFORMATION IN THE LIKELIHOOD FUNCTION OF THE SIR VIDEO TARGET TRACKING FILTER
Fuenmayor Bello, Jesyca (2016)This thesis is focused on visual target tracking. Visual target tracking has been widely studied. The main idea is to be able to determine the target's location from a video sequence. Techniques such as the Kalman Filter ... -
