Summary<br />

This three-day course addresses digital signal processing<br />

theory, methods, techniques and algorithms with practical<br />

applications to ELINT. Digitizing, filtering, demodulation,<br />

spectral analysis, correlation, parameter measurement,<br />

effects of noise and interference, display techniques and<br />

additional areas are included. Directed primarily to<br />

ELINT/EW engineers and scientists responsible for ELINT<br />

digital signal processing system software and hardware<br />

design, installation, operation and evaluation, it is also<br />

appropriate for those having management or technical<br />

responsibility .<br />

Instructor<br />

Brian Moore has over 25 years experience in systems<br />

engineering in EW, ES / ESM, and ELINT, including electronic<br />

attack and radar systems. He has a BSEE from Michigan<br />

Technological University and an MSEE from Syracuse<br />

University. Mr. Moore has performed system engineering and<br />

analysis to integrate new EW technology and techniques with<br />

existing systems and platforms throughout his career. In<br />

addition, Mr. Moore provides technical inputs to the<br />

government for ELINT R&D and provides consulting for EW<br />

system architecture and processing, specific emitter<br />

identification and tracking, feature extraction, intentional<br />

modulation on pulse, signal detection, and wideband / LPI<br />

processing. Mr. Moore has performed various EW/ESM<br />

systems engineering, analysis, development, integration, and<br />

test efforts (INEWS, F-22, A-12, B-2, special projects). Mr.<br />

Moore is currently the Senior Vice President and Technical<br />

Director for a major research company.<br />
