Digital RF memories (DRFMs), are arguably, the most important technology and a driving force in electromagnetic maneuver warfare (EMW). This course examines both the design of the DRFM as well as the technologies and strategies used to create superior false target decoys. In addition, machine learning and the capability to autonomously detect and classify in real-time, enemy systems that use waveforms and frequencies not previously encountered or anticipated is emphasized.

Who should attend:
This course is intended primarily for engineers and scientists interested in the technology and design of digital RF memories and electronic warfare receivers including the techniques used in electromagnetic maneuver warfare (EMW). Attendees should have a good knowledge of radar systems and signal processing. Example problems are worked out to demonstrate the concepts and further the understanding of the material being presented. Some MATLAB programs are used to help students clarify difficult concepts.
