Kenneth M. Duvall, Ph.D.
Principal Scientist

Dr. Duvall joined PROTEUS in January of 2005 and currently works as both a program/technical manager and technical contributor on projects involving signal and information processing. For more than 20 years he has devoted the majority of his time to the development of analytical-support systems for an indications-and-warning (I&W) center in the Washington, DC area. These systems perform a variety of functions including text processing, reduction of data to compact forms for database entry, automated quality control of database entries, automatic data analysis and report generation, fusion of all-source data, and both real-time and off-line support of analysis-center operations. He remains involved in the maintenance and modernization of these systems, dividing his time between development facilities in Mountain View, CA and the Washington, DC area.

Dr. Duvall has over 30 years of experience in the design and development of techniques for signal and information processing and the application of those techniques to problems in reconnaissance and surveillance. He received his Ph.D. in electrical engineering from Stanford University where he did research on adaptive antennas at the Information Systems Laboratory under the direction of Professor Bernard Widrow. The particular topic of Dr. Duvall's research was desired-signal cancellation in adaptive beamformers (ABFs). When adaptation rates are high, signal cancellation arises in standard ABFs due to interaction between the desired signal and interference; this phenomenon can significantly affect the quality of the beamformer output signal. Dr. Duvall devised a novel ABF structure that avoids signal cancellation and thus provides an improved output signal.

In their leisure time, Dr. Duvall and his wife enjoy traveling, both within the USA and abroad. Western Europe is a particular favorite.
