Creeping Wave Propagation On Cylindrical Radiating Structures
(2019-08-01)
Weather radar is a powerful tool for detecting hazardous weather that may impact
the lives of many. Most weather radars used by meteorologists today rely on a
mechanical sweep to obtain volumetric data. This mechanical ...
A fuzzy logic algorithm for classifying bird and insect radar echoes at S-band
(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) ...
UAV-Based In Situ Antenna Characterization: Analysis and Design Requirements
(2018-05-11)
This thesis proposes to characterize antennas in situ with Unmanned Aerial Vehicles (UAVs), especially within the framework of weather radar and 5th generation wireless systems (5G) antennas. Specifically, it is concerned ...
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 ...
Nonlinear Amplifier Amplitude Modulation Distortion Mitigation Techniques
(2022-05-13)
High peak-to-average power ratio (PAPR) waveforms present a challenge to
radar systems in which high power amplifiers operate in saturation to increase
power efficiency. Previous works have demonstrated a marked reduction ...
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 analysis of the information content of radar detection
(2022-08-04)
The availability of the electromagnetic spectrum (EMS) was an unseen issue in the past,
as there was sufficient spectrum access to suit the needs of its’ consumers. Today, the use
of the EMS has been become integrated ...
Methods for Control, Calibration, and Performance Optimization of Phased Array Systems
(2022-05-13)
Phased array radar systems have proven advantageous in a variety of research applications, offering faster volume scans and unparalleled time-resolution as compared to traditional parabolic dish antenna systems that rely ...
Analysis of the Finite Array on the Scanning Performance of Phased Array Antennas
(2020-12-18)
Modern high performance phased array antennas require large apertures to achieve both high gain and narrow beamwidth. It is not practical to manufacture such large apertures, so the full array is composed of smaller ...
DESIGN AND IMPLEMENTATION OF AN ALL-COTS DIGITAL BACK-END FOR A PULSE-DOPPLER SYNTHETIC APERTURE RADAR
(2020-05-08)
Radar imaging techniques employing synthetic aperture radar (SAR) are ubiquitous in applications such as defense, remote sensing, space exploration, terrain mapping, and many others. However, to obtain fine image resolution, ...
