AESA vs. AAM

Much has been mentioned about the AESA’s ability to accurately focus microwave energy at great distances. Supposedly, this could allow it to fry the electronics of an enemy plane or missile.

In the case of Air-to-Air Missiles (SARH or active homing modes) which are dependent on receiving radar returns from the intended target, is hardening really possible or will an AESA just overpower its electronics rendering it useless?

Don’t agree with the “airborne can’t fry” statements. It is exactly something that is looked into for JSTARS and AWACS types. It’s very complex, but let’s just say that the propagation of unhardened COTS semiconductor electronics of ever decreasing structural size doesn’t increase survivability, esp when the characteristics of that COTS hardware can easily be studies by the potential enemies. And effective shielding is rapidly becoming complex and heavy when required over a wide frequency and peak power range. The power/duration requirement for a physically destructive pulse against modern semiconductors is surprisingly low if you know the right frequency. In the end a mission kill caused by the destruction of some unhardened/shielded subsystem is (almost) as effective as a flak shrapnel in the pilot’s butt.

ELECTRONIC ATTACK

Radar Glossary

Radar — Electronic Attack

Information on Electronic Attack

Electronic attack (EA), previously known as electronic counter measures (ECM), is conducted on radar systems to reduce or prevent the radar’s use of the electromagnetic spectrum effectively.

Well, if an AESA can really fry or otherwise damage or impair the radar receiver on an incoming AAM, then it fulfills the defininion of electronic attack… unless, of course there’s another, more accepted definition/term.

It cant. It doesnt provoke phisical damages to a radar, you are going to need an EMP nuclear strike to do that (or an HARM/JDAM/rock/whatever/something kinetic).
Pit already explained it very well, its the old ECM jargon/techniques all over again.

Electronic Attack is not about destroying enemy’s electronics system due to highly directional EM attack. Electronic Attack (EA) is new US Joint Chief term of Staff for what was earlier know as Electronic Counter Measures (ECM), and it’s just that.

Some new radars would be capable of doing highly directional JAMMING against different air targets, whithin its bandwidth limitations (for AESA, it’s very high)

Electronic attack is one of those hush-hush topics so we are just left to speculate on the possibilities.. but I’ve no doubt that the US is capitalizing on its lead in AESA tech to test its ability vs. different kinds of airborne targets. This could do to radar-guided missile what DIRCM does to heat-seekers.. funny, if this works and DIRCM works, then you take missiles out of the equation. Pilots could be getting their kills using DEWs or old-fashioned cannon.:diablo:

At least for airborne radar we can be sure it is impossible in foreseable future. We know what ground based radars (which have magnitude higher power and better beam focusing) cant do it – so airborne radars dont have a chance. Yet.

But when another step in radar technology happens – who knows… Thought i bet laser technology have much brighter future here.

interesting idea. It would make sense for aesa equipped fighters to carry ir missiles that have some range on them if they have to go up against peers. ir amraam? or dual mode amraam?

Well you can bet that new types of multimode seekers will be coming out in the effort to counter electronic attack, etc… Of course for the time being, it’s a not widespread ability that most fighters would have to deal with.
