Radar Network Synchronization And Imaging Using Semiconductor Laser System, Meesha Gupta Jun 2021

Radar Network Synchronization And Imaging Using Semiconductor Laser System, Meesha Gupta

Honors Theses

The purpose of this project is to report the software implementation of radar network synchronization and imaging using a semiconductor laser system. We compare different radar configurations and methods to generate laser chaos.

The monostatic radar configuration has limited capabilities of detecting targets with low radar cross-sections. This configuration is also vulnerable to intentional interference. In contrast, a radar network where multiple radar transceivers (nodes) are placed strategically can yield superior detection. This radar network can also extract additional information about the target, such as its size and shape. However, synchronizing the nodes in the radar network poses a significant …


Circuit Breaker Failure Analysis System, Marlie Norbrun Jun 2021

Circuit Breaker Failure Analysis System, Marlie Norbrun

Honors Theses

Norbrun, Marlie Circuit Breaker Failure Analysis System. Electrical, Computer, and Biomedical Engineering Department, June 2021.

ADVISOR: Professor James Hedrick

Electrical malfunctions are one of the leading causes of domestic fires in the United States. Between 2012 and 2016, electrical failures were responsible for 44, 860 residential fires (Richard Campbell, “Home Electrical Fires”). All electrical circuits contain circuit breakers, which are used as safety mechanisms to interrupt current flow when a fault develops. It is not always possible to determine if an electrical fire resulted from a circuit breaker malfunction. Thus, it would be beneficial to have a cost-effective and user-friendly …


An Open-Baffle Motional Feedback Loudspeaker, Matthew Quinlivan, William Harvie May 2021

An Open-Baffle Motional Feedback Loudspeaker, Matthew Quinlivan, William Harvie

Honors Theses

A dynamic loudspeaker mounted in an open baffle has the same parameters as a loudspeaker in free space. A subwoofer mounted in an open baffle has a small total quality factor and therefore the frequency above which the driver has a significant output is too high despite the subwoofer's low resonant frequency. To address this issue, we implemented a motional feedback circuit with the goal of introducing both velocity feedback and acceleration feedback into the loudspeaker system and thus altering the resonant frequency and total quality factor of the system. After verifying the efficacy of our feedback circuit with computer …
