John F. Doherty

John F. Doherty is a Professor in Electrical Engineering, specializing in signal processing and radar systems. His research spans interdisciplinary applications including sonar tracking, steganography, and speech recognition.

• Key research areas: Data assimilation, spread spectrum, and empirical mode decomposition
• Collaborations: National Science Foundation-funded projects with J.D. Mathews at Arecibo Observatory

Research Interests: Professor Doherty's work focuses on real-time multi-mode data assimilation for geophysical radar systems, interference suppression in signal processing, and covert waveform design for sonar applications. His recent studies explore entropy-based speech quality metrics and compressed speech analysis for speaker recognition systems.

Grants & Projects: Lead NSF-funded projects on Arecibo radar systems (2001-2009), developing efficient data assimilation techniques. Collaborated on multi-mode radar systems and sonar steganography.

Publications: Over 88 research outputs with 1075 citations. Recent works include nulling algorithms for radar ambiguity functions and covert communication techniques in sonar systems.
