Shannon Blunt

Blunt grew up in New Madrid, Missouri, and was one of five valedictorians in the class of 1994 at New Madrid County Central High School. He then received B.S., M.S., and PhD degrees in electrical engineering from the University of Missouri in 1999, 2000, and 2002. From 2002 to 2005 he worked as a radar engineer in the [https://www.nrl.navy.mil/Our-Work/Areas-of-Research/Radar/ Radar Division] of the U.S. Naval Research Laboratory (NRL) in Washington, DC, joining the University of Kansas in 2005. His research interests are in sensor signal processing and system design with a particular emphasis on waveform diversity and spectrum sharing techniques, having made a variety of contributions that have been deployed in operational radar and sonar systems.

With a focus on the intersection between theoretical signal processing and radar systems engineering, Blunt has led the development of numerous radar research contributions, with many of these being experimentally demonstrated using open-air measurements. Some noteworthy examples, many of which are patented/patent-pending, include:
