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 ...
Deep Learning for Weak Target Detection in Range-Doppler Data
(2022-05)
A consistent issue for detectors in radar systems is how to correctly distinguish target signals from random noise. This is especially true for weak targets with low signal-to-noise ratios (SNRs). Traditional target detection ...
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 ...
Accelerating Distributed Synthetic Aperture Radar Data Simulations Via CUDA
(2022-05)
A general simulation of distributed synthetic aperture radar (DSAR) data is useful to evaluate the theoretical performance of a DSAR system and its underlying algorithms without a deployed system in place. Simulating DSAR ...
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 ...
Exploring Tornado Debris Signature Hypotheses Using Radar Simulations and Large-Eddy Simulations
(2021)
Tornadoes can loft various types and sizes of debris, sometimes resulting in a polarimetric radar signature called the TDS (Tornado Debris Signature). The presence of a TDS in the radar data can help confirm the occurrence ...
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, ...
The Intersection of Radar and Communications: A Study on Spectrum Management for Addressing RF Interference
(2023-05-12)
The radio frequency (RF) spectrum is a fruitful yet competitive frontier that enables technologies like 5G, Wi-Fi, Bluetooth, GPS, long-range telescopes, microwave ovens, radar, and more. With finite supply and increasing ...
