RDRtec was founded in 2006 for the purpose of performing basic and applied scientific research, and providing science and engineering consulting to Government agencies and private industry.

Dr. Sid Theis - President & Founder

Dr. Theis has extensive experience in active element phased array radar systems, mode and waveform design, simulation and system design. Current focus areas include radar architectures, algorithm development, and performance studies. He has over 30 years of experience in radar systems engineering.


Bill Norvell - Senior Systems Engineer (Consultant)

Mr. Norvell has extensive experience in radar system electronic scanned arrays, solid state transmitters, digital signal processing, GaAs microwave components, antennas, IFF, missile systems design; guidance and control, RF and EO seekers, fuzing, ECCM, targeting, RF and sensor MEMS including inertial and microwave. He has over 40 yrs experience.


Gaylen Williams - Senior Manager

Mr. Williams has extensive experience in the development and management of advanced radar systems including the APS-137/APY-10, SPY-3, and earlier APS-116, APS-134, and APS-137 systems. Advanced technology experience includes development of Inverse Synthetic Aperture Radar (ISAR), Automatic Radar Periscope Detection & Discrimination (ARPDD), Horizon Extension Surveillance System (HESS) and commercial development of Digital Light Processing technology. He has over 35 yrs experience.

Wayne Miller - Senior Systems Engineer

Mr. Miller has over 40 years of experience in radar system design and analysis. He has developed numerous radar performance analysis programs including RADAN. He has extensive experience in sea clutter modeling, Inverse Synthethic Aperture Radar (original developer), SAR, and Terrain Following/Terrain Avoidance (TF/TA) radar systems.

Robert Hancock - Senior Analyst

Mr. Hancock has over 40 years experience in radar system design,
development, and evaluation, including over 35 years in the development
of detailed radar simulation modeling tools. He has participated in
numerous US DOD funded radar design and development efforts. He brings with him the expertise and software that has developed commercial software packages for antenna/radar system design and simulation. Those products include RAST, PAAS, and IRSS which are widely used by industry, government agencies, and universities. Mr. Hancock is the lead engineer on the AFRL sponsored RLSTAP simulation tool development effort. Mr. Hancock has participated in numerous Space-Based Radar design and evaluation efforts funded by DARPA, AFRL/Rome, and Grumman/Bethpage from 1977 thru 1986 and more recently for the Space Radar Integrated Program Office.

Michael Matuson - Senior Software

Michael Matuson is RDRTec lead for software process, simulation architecture design, and software design. He began his career at the Applied Research Laboratory at the Pennsylvania State University as a Research Assistant working in the field of underwater signal propagation and signal design where he developed advanced signal processing algorithms for use in sonar imaging. At Texas Instruments Defense Systems, where he spent 15 years, he was an advance sensor simulation design expert. He was involved in modeling passive RF sensors that included interferometer angle estimation, radar sensors and imaging infrared sensors as well as developing high fidelity simulations for a wide variety of purposes. He developed imaging processing algorithms for fire-and-forget technology missiles and autonomous target recognition algorithms for missile and other airborne platforms. In 1999, he became an independent contractor for designing simulations for real time visual fidelity and high fidelity radar models. He joined RDRTec in 2006.


Ron Jahn - Signal Processing

With Raytheon (formally TI) he has 22 years of experience developing advanced signal processing algorithms and real-time software, data analysis, and system-level requirements analysis. Ron has experience in developing real-time radar imaging modes and  in using multi-channel signal processing approaches for detecting weak signals in the presence of interfering signals and noise.


Jeff McKay - Software Engineering

Mr. McKay has extensive experience in software development and computer systems administration. He was the lead programmer in developing the RAST-K and RLSTAP simulation tools, which are widely used in the defense industry. He is responsible for simulation tool maintenance and upgrades, configuration management, acceptance testing, documentation, delivery preparation, and customer support.
