The Hammster
Senior Engineer

BSEE : University of Massa chusetts/Dartmouth, 1973 w/Distinction
MSEE : Virginia Tech, 1977

Professional Engineer, Commonwealth of Virginia

Subsystem architecture : Extensive experience with requirements and interface definition, and hardware and software functional partitioning.

Analog and digital signal processing : Experienced with filter design, spectral processing, stochastic processes and control systems.

Analysis : Experience in the design of low noise systems. Often called upon to solve system power and grounding problems.

Electronics design : Experience in analog and digital circuit design.

Integration and test : Experienced in requirements verification and tracking.

Programming : Experienced Pascal and APL programmer. Familiar with object oriented programming.

1997 to Present: Cognizant engineer to the prime contractor for the spherical array sonar of the New SSN.

1992: On international assignment to the UK. Responsible for the readiness of the test facility for the Merlin EH101 helicopter, including the specification and delivery of signal processors for real time environment and track simulation/stimulation to the sensors of the sonobuoy processor, the active dipping sonar, and the scanning radar.

1988: Architect for the AN/BSY-2 (Seawolf) active sonar system and lead development engineer for the system analog electronics that control, switch, and monitor the high power acoustic amplifiers. The Hammster's innovative and low-cost technical approach was responsible for wresting the long held active sonar business away from the Raytheon Submarine Signal Division.

1983: Designed the first switched capacitor filter integrated circuit within IBM under IR&D. Fabrication was a first pass success. The design incorporated a new method developed by the Hammster for mapping filter poles and zeros to switched capacitor elements. Also under IR&D, the Hammster developed techniques for improving the performance of sigma-delta analog to digital converters.

1980: Lead system engineer responsible for the architecture and specification for the acoustic front end of the primary AN/BSY-1 (SSN 688) submarine phased array sonar system. This architecture introduced advanced diagnostics, digital signal processing, and microprocessor control now incorporated into sonar systems across the fleet. Received outstanding technical achievement award for delivering the first sonar system to meet its extremely low self noise requirements.

1976: On leave of absence at Virginia Tech as a graduate research assistant developing adaptive control methods of large flexible space structures. Published two correspondences in IEEE Transactions.

1973: Development engineer in the design and debug of the acoustic front end of the AN/BQQ-6 (Trident) submarine sonar system.

The Hammster has twenty five years experience in both the system and development design of analog and digital signal processing equipment, primarily related to active and passive sonar systems. With a background extending from high-function high-performance analog and digital circuit design to major subsystem architecture to integration and test, the Hammster is called upon to solve system noise problems, develop feasible system-to-sensor implementations, and define test system requirements.
