Metal-coated dielectric fibers that when dispensed in large numbers can produce strong radar echoes.

A flare that burns with an IR wavelength similar to the target aircraft IR signature.

A Direct Infrared Countermeasures System Demonstrator.

Infrared counter measure system that tracks and directs energy towards the threat.

A decoy attached to a thin cable, which can gradually be reeled out behind the aircraft, to confuse an enemy and draw his radar, or the seeker of an approaching radar guided missile

Technology developed to protect aircraft against attack from sophisticated Infrared guided missiles

DIRCM systems consist of a missile approach warning system that detects the launch and approach of the missile, and a director system, e.g. a turret, that is cued to track the approaching missile

System produced by Northrop Grumman and BAE Systems to protect aircraft from infrared homing manportable missiles.

Division of EW involving actions taken to prevent or reduce an enemy’s effective use of the EM spectrum, through the use of EM energy.

Division of EW involving actions taken to ensure friendly effective use of the EM spectrum despite the enemy’s use of EM energy.

Division of EW involving actions taken to search for, intercept and identify Electromagnetic (EM) emissions & locate their sources for the purpose of immediate threat recognition.

Only enable and inhibit missile firing/bomb release.

Only enable or inhibit the fuze settings on flight.

Only enable and inhibit safety critical store functions which are commanded by the aircraft over the data bus interface.

The store RT address is coded at MSI and ASI levels

The store RT address is coded at ASI levels.

Each store comes with its own RT address code from supplier.

It is an active sensor.

Several sensors provide full coverage.

It is a passive system

There are not natural background sources that can obscure the emissions.
