Start Date 1: 11/05/2019 8:30 am


Location Course 1: Columbia, Maryland

Course Length:





This four-day course addresses digital signal processing theory, methods, techniques and algorithms with practical applications to ELINT. Directed primarily to ELINT/EW engineers and scientists responsible for ELINT digital signal processing system software and hardware design, installation, operation and evaluation, it is also appropriate for those having management or technical responsibility.

What you will learn:

  • EW/ELINT receiver techniques and
  • Digital Signal Processing
  • Application of DSP techniques to digital receiver development.
  • Key digital receiver functions and
  • Fundamental performance analysis and error

From this course you will obtain the knowledge and understanding of digital signal processing concepts and theories for digital receivers and their applications to EW/ELINT/ESM systems while balancing theory with practice.
