Information jamming in Electronic warfare: Operational requirements and techniques

Information jamming in electronic warfare is a form of electronic attack where jammers radiate interfering signals toward an enemy's system, blocking the receiver with highly concentrated energy signals. The purpose of information jamming is to interfere with the enemy's effective use of the electromagnetic spectrum. This information can take the form of voice or non-voice (e.g., video or digital format) communications, command signals to control remotely located assets, data returned from remotely located equipment or the location and motion of friendly or enemy assets. Information jamming is a “soft kill” because it temporarily makes an enemy asset ineffective but does not destroy it. Information jamming can be applied from air, sea, land, and space by manned and unmanned systems, and can target communication, radar, or other services. Within the information operations construct, information jamming is an element of offensive and defensive counter information in Electronic warfare. This paper provides operational requirements and technique affecting parameters of jamming for optimal adaptation in modern warfare scenario. It also provides necessary guidelines to users particularly from defence sector to allow them to upgrade their exiting capabilities and complement future war situations more effectively with lesser human interventions.
