gave assignments and supervised their activity. Analyzed effects of EMI on ship
subsystems.

Aug 2000 to May 2002.
Worked
on a Ph.D. in signal processing. (ARMA, Wavelets, optimum receivers)

System
analyst for the ground based radar system of THAAD which is an anti-missile system.
Determined the best use of multiple beam search. Determined
that the split tracker used at that time was inefficient. Put together a radar
simulation suitable for critical design review. This simulation analyzed track
initiation, Kalman filter performance, track association, and false alarms and detection.
Looked for a way to reduce the clutter resulting from an interception of a RV by a kill
vehicle through the use of ARMA’s.
Technical
Specialist
Served
as technical lead and system analyst who coordinated the efforts of five companies and
research activities of individuals within McDonnell Douglas to support the development of
an Airborne Early Warning Radar. The project
involved analysis and design of phased arrays,
adaptive array processing, electronic counter measures, low probability of
exploitation signals and analysis of anti-radiation
missile threat. A phased array was produced and initial tests were
conducted and expected performance was achieved.

Senior
Engineer
Aug 1979 to May 1981
Modeled
radar cross-section of radomes, inlets, antennas, and fuselage. Used technologies such as metallic radomes, radar-absorbing structures (RAS), radar absorbing materials (RAM), and shaping to
minimize backscatter. Made analytical improvements to prediction methods which were used
by aeronautical engineers in their design of future planes.
