Neutralisation

Front 4

Define Electronic Jamming

Back 4

The deliberate radiation, re-radiation or reflection of electromagnetic energy to impair the effectiveness of electronic devices, equipment and systems being used by the enemy.

Front 5

Define Electronic Deception

Back 5

The deliberate radiation, re-radiation, alteration or reflection of EM energy to confuse, distract or seduce an enemy or its electronic systems.

Front 6

Define Electronic Neutralisation

Back 6

The deliberate use of EM energy to either temporarily or permanently damage enemy devices that rely exclusively on the EM spectrum

Front 7

Define Electronic Defence (ED)

Back 7

ED involves the use of EM energy to provide protection to friendly forces and to enable effective friendly use of the EM spectrum.

Front 9

Define Passive EPM

Back 9

It must be remembered that equipment must be protected from Friendly as well as Enemy EW Activity and operator training can be the most effective way to counter enemy EA

Front 10

Define Active EPM

Back 10

Achieved through measures such as frequency hopping, burst transmission and changing the polarization of radar pulse

Front 11

Define EMCON (Emission Control)

Back 11

EMCON is the selective and controlled use of EM, acoustic or other emitters to optimise Command & Control (C2) capabilities, whilst minimising detection by an enemy’s sensors for Operational Security (OPSEC), to minimise mutual interference among friendly systems, or to execute a military deception plan.

Front 12

Define Electronic Masking

Back 12

Controls EM radiation on friendly frequencies, to protect the emission characteristics of communications and electronic systems against an enemy’s ES e.g. Encryption

Front 13

Define Electronic Support (ES)

Back 13

“…….the division of EW involving actions tasked by, or under direct control of, an operational commander to search for, intercept, identify, and locate or localize sources of intentional and unintentional radiated EM energy for the purpose of immediate threat recognition, targeting, planning, and conduct of future operations.”
