F-22A Raptor's APG-77 radar

Hi all

Nowadays, people have discussed, in some Aviation forums, about the Raptor's APG-77 supposed burn-out enemy's radar capability. Can anyone confirm if that information is true or not.

Thanks in advance.

The F-22 doesn't have a conventional radar with one antenna up front. It has a large number of solid state transmitter/receiver modules which are capable of very fast switching speeds. It is computer controlled and very configurable. You do the math.

All AESA Radar system if programmed for, are capable to be used as MicroWave oven on enemy targets, also may be configured as HighSpeed Data relays, and as a vey powefull multi-mode Jammer.

Marcelo,

A lot of specific things about the Raptor is considered sensitive and cannot be discussed, especially in an open forum. A good rule of thumb is anything regarding specific capabilities and numbers such as "sensors" and aircraft performance/capabilities is getting in the uncomfortable range.

Lookup the Aviation Week & Space Technology magazine. It's publicly available, from official source, and has a lot of informative articles about the F22, to include some general publicly/officially released info on the radar.
Cheers!

Please be aware that just because something is available on a public source doesn't mean it's non-classified. Otherwise someone could leak something classified on this site and it would then make it okay to discuss. I had a buddy that just forwarded a link to a public F-117 website and it had classified info on it. It was a nightmare for him with all the investigations and temporary revocation of his security clearance. He was a Chief at the time but I would imagine that it would kill the career of a young airman or junior NCO.

I remember the burn outs that hung out in the high school parking lot always smoking something. To think that their R&D concepts are now bearing fruit.

The short answer for future AESA concepts is that we are only now figuring out all the neat things that are possible with it when mated to the right network and info system. What started out as a sensor and weaponeer helper for missiles has been discovered that it is of course a very capable transceiver for any number of uses, C2-ISR, ECM, ECCM, ESM, maybe even someday ESPN. Use your imagination. AV Week had an article about that very topic not long ago.

Yep. I heard scuttlebutt that the drivers who are big golf fans (and who isn't, quite frankly?) were gonna try to add the live Golf Channel feed from Augusta next month. I guess the GC wasn't part of their "basic" package so I assume they're gonna need an amendment to the latest Defense Appropriations Bill for the upgrade.

As long as I can get SportsCenter, and Monday Night Football, I'll be happy!

Seriously though...Dude, asking questions about a radar from an aircraft that is still mostly classified? On a public foxtrotting forum?

AC? Shev, is that you?

To Err is Human. To Forgive is NOT ACC Policy.

Nonononono TC, Shev would be asking YOU for details. If you want to go back through the forums and see him poke and prod for RCS numbers. I believe the real question should probably, is it possible to overload a radar. To heck with burning it out, the ABL has that one covered . Will a radar only show one location of a target regardless of how much power is put into it? Hmm, ok that's a little weird. If you beam power INTO an enemy radar can you trick it into thinking you're larger than you are? Or better yet, think you are everywhere if you beam enough power into it? Can you do the same thing, but use a principal of destructive interference into it to decrease your signature? That doofing isn't it?

This may be classified info, if it is, just smack me. How does jamming a radar work? Does a radar just beam out a ton of power to interfere the the missile/enemy radar signal? I don't want specific, and am not a troll you guys know this. I just ask stupid questions. I was just wondering if the basic principle was public? Again smack me if nothing should be said about this.

*SMACK* *SMACK*

Won't comment on how it's done today, but back in "Dubya Dubya Two" the Brits used foil strips of varying lengths (based on intel about Gerry's radar capabilities) to cause German screens to look like your old black and white TV screen that lost the signal. Nothin' but snow and noise. And in some cases you made Gerry think you were somewhere you weren't.

(will now wait for a smack from someone, preferrably Vypergrl )

AYE AYE CAPTAIN, SHUTTING UP. Yeah, I figured there might be some information about the basic jamming stuff. I will shut up and ask no more.

The basics of ECM are pretty common knowledge (signal? meet more powerful signal.) The devil is in the details. And that's why it's best for people who KNOW the details not discuss them here.
