Electromagnetic support using software-defined radio

  • 1 Bulgarian Defence Institute Sofia, Bulgaria

Abstract

The essence and main characteristics of Electromagnetic Support (ES) are examined, as well as its place in Electromagnetic Warfare (EW). The main elements of ES such as electromagnetic reconnaissance, direction finding and threat warning are examined. A definition and basic terms for software-defined radio (SDR) are given. The architecture and main characteristics of SDR are examined. Has been made a prototype of SDR used in electromagnetic support.
