Employment History


During the period from 1981 through 1989, I worked in the Radar Systems Laboratory of the Radar and Communications Division (Division 14---later Division 1F) of Hughes Aircraft Company in Fullerton, California. My work there involved designing and analyzing ground based radar systems, with a strong emphasis in radar signal processing, radar scattering, signal processing and pattern recognition techniques for radar target recognition, target tracking and trajectory estimation, and ISAR techniques. During this time, I worked with the AN/TPQ-36 and AN/TPQ-37 Firefinder radar systems and the TPQ-36A Low Altitude Surveilance Radar (LASR) system, performing theoretical and experimental studies on their application to target identification and tracking slow-moving and hovering targets in high clutter environments. In addition, I was envolved in the proposal , competition, and early system design for the Foward Area Air Defense Gound Based Sensor (FAAD-GBS), which is now fielded as the U.S. Army's AN/MPQ-64 Sentinel. From 1984 - 1988, I was also a Howard Hughes Doctoral Fellow at Caltech., where I worked in the areas of information theory and radar..

Since joining the faculty of Purdue University, I have focused my research interests on problems in radar and sonar signal processing, information theory, optical and microwave speckle, radar signal design, optical communications, communications systems, and statistical signal processing.
