Richard D Teichgraeber, Ph.D., P.E. is an independent consulting engineer; recently retired from Lockheed Martin Aeronautics Co. He is a Life Senior Member of IEEE and a contributing SPIE member. He has been a registered engineer in Texas since 1980. In college he was a member of Sigma Tau and Eta Kappa Nu. He taught an EE laboratory course in his last year of graduate school. His 40 years at General Dynamics/Lockheed Martin were focused in applied research, primarily insertion of new concepts and software technology into the fighter cockpit. His contributions included: developing simulation software to validate flight programs for the F-111, F-16 and F-35 fighter avionic systems; as Program Manager for three USAF-sponsored R&D programs; management and development of three sensor correlation algorithms for pilot situation awareness on advanced F-16 versions. He collaborated and/or wrote over 20 technical publications regarding power system stability, navigation systems, Kalman filtering applications, avionic simulations and models, artificial intelligence and sensor correlation algorithm applications. His current research interests include: correlation and fusion algorithms, target tracking and identification algorithms and performance metrics for fusion algorithms. He is currently a co-chair of the annual SPIE conference, Signal and Data Processing of Small Targets. Richard serves as a Trustee of the Kansas State University Foundation and is an active member of several alumni and Foundation groups. He presented a Distinguished Lecture to the College of Engineering there in 2006. He is a strong proponent of engineering education and helping students achieve their greatest potential, i.e., by “giving back.” He and his wife have endowed the University with an annual scholarship for Jr/Sr level electrical engineering students.

Lecture Title(s)

Evolution of Flight Programs: Still in Real-Time?
Airborne computer programs have evolved considerably in the last 50 years. From analog, hard-wired circuits to multiplexed, digital data and images all integrated digitally – just what the pilot needed or not?
System complexity and massive software procedures lead to flight programs which marginally get the data to the pilot in real-time. These programs still require detailed test procedures carried out in ground-based laboratories before actually being flown. Are we on the right track here?

Sensor Correlation: A Prelude to Track Fusion
Sensor track/report correlation is a necessary step towards track fusion and generation of a system track file. Correlation follows an ordered procedure in comparison of candidate sensor tracks with established tracks. The procedure is defined along with several examples of track correlation. If correlation were chosen as the end product, assignment of track attributes is considered.

Metrics for Track Correlation: Why so important?
Track correlation metrics are crucial in the procedure for evaluating correlation and fusion algorithm performance. The metrics aid in condensing literally megabytes of data into a simple figure of merit. The metrics must be timely and be representative of the process under evaluation. The cases of ground and airborne correlation procedures are discussed as well as representative meaningful and irrelevant metric examples the engineer has encountered in practice.
