DRFM Executive Overview

Course Description

This one-day abridged course provides a detailed overview into Digital Radio Frequency Memory (DRFM) technology focused on Electronic Warfare (EW) applications for radar Electronic Attack (EA). Key fundamentals covered include theory of operation, common EA techniques, and a summary of hardware architecture options typically utilized in modern Electronic Warfare (EW) systems. Examples of DRFM EA use cases are presented to provide insight into the effects DRFM attack can have on coherent radar systems. Potential Electronic Protection (EP) techniques to protect radar systems from a DRFM jamming attack will also be introduced.
