Generation of Synthetic Antenna Apertures In Swarm Unmanned Aerial Systems Using Tight-Coupling
(2022-05-13)
Relative to their various land and air-based counterparts, swarm unmanned aerial system (SUAS) platforms, being comprised of many separate airborne bodies, or elements, possess a number of unique and advantageous ...
Frequency-agile filtering antennas for S-band and X-band applications
(2023-05-12)
Multi-functional, highly flexible, and tightly integrated Radio-Frequency Front-Ends (RFFEs) are at the forefront of the current developments to improve the performance of next-generation wireless RF systems. In the past ...
Multiclass Bone Segmentation of PET/CT Scans for Automatic SUV Extraction
(2021-12-17)
In this thesis I present an automated framework for segmentation of bone
structures from dual modality PET/CT scans and further extraction of SUV
measurements. The first stage of this framework consists of a variant of ...
An Implementation of Real Time Testbed of Cognitive Switch for Multi-user FSOC Link
(2021-08)
Free-space optical communication (FSOC) has been a popular alternative for radio frequency communication technology. Multiplicity and atmospheric turbulence are known to introduce fluctuations to FSOC link performance. ...
A correlation-based Inversion Method for Aerosol Property (CIMAP) Retrieval from AERONET Measurements
(2021-08-05)
We developed a principal-component based inversion approach – A correlation-based Inversion Method for Aerosol Property (CIMAP), to retrieve aerosol properties from AERONET measurements of aerosol optical depths (AODs) and ...
GPS disciplined RFSoC synchronization, timing, and performance characterization in bistatic radar systems
(2023-12-15)
Distributed radar geometries offer multiple advantages over monostatic pulse-Doppler radar, but synchronizing frequency and timing for transmitting and receiving nodes in a distributed system is required to more accurately ...
Classifying Wi-Fi from Raw Power Measurements Using a Neural Network Adapted from WaveNet
(2021-08-05)
Research to identify coexisting wireless devices is becoming increasingly important, in part due to the yearly increase in internet users and wireless devices. Various machine learning algorithms, including neural networks, ...
Digital predistortion of wideband radar waveforms
(2021-12-17)
As demands for increased radio frequency system performance have grown over time, sufficiently mitigating the distortion introduced by high power amplifiers has proven to be a major challenge to overcome. Digital predistortion ...
Spurious suppression techniques in integrated and embedded microwave components
(2021-08-05)
To increase bandwidth and mitigate interference in a crowded electromagnetic spectrum, future microwave systems will move to higher operating frequencies. Because lumped elements perform poorly at high frequencies, designers ...
