Air Force systems like the AlE-50 towed decoy and Large Aircraft Infrared Counter-Measure (LAIRCM) are designed to degrade the performance of terminal guidance radar
and electro-optical sensors housed within missile seekers.
Considering the exact expression is fairly complicated, we simplify it combined with the typical range of terminal guidance radar
The reason was they knew if they turned on that guidance radar
, they were going to get a missile.
A guidance radar
forms a track file on a target (i.
Figures 16 and 17 show the Grill Pan, which is a multiple-target X-band tracking and guidance radar
using a 10,000-element space-fed transmission lens.
The 9S36E target illumination and guidance radar
(Tigr) can be elevated up to 21 metres and covers [+ or -] 45[degrees] in azimuth.
The combat means of the system include the 30N6E1 phased-array illumination and guidance radar
(NATO designation: Flap Lid B) and 5P85 launchers (up to 12 pieces) with 48N6E SAMs kept in launching/transporting containers.
A typical battery has a 30N6E1 illumination and guidance radar
and eight (although some batteries have twelve) 5P85ME/SE launchers, each with four ready-to-fire 48N6E missiles.
All ballistic missile defense systems consist of a network of tracking and guidance radars
, and the interceptor launchers.
Active techniques use electronic attack to protect these platforms, while the passive techniques employed in EP work to detect hostile electronic systems, such as fighter radars or surface-to-air missile guidance radars
, to alert a platform that it may be under attack.
