Anytime

Any chance of a new forum for general discussion, ie stuff not related to Lockon?

I have no idea who this guy is but he does an awesome job! NFL? http://www.youtube.com/watch?v=yYN6K4ylXUQ

http://www.kockums.se/SurfaceVessels/visby.html swedes have been doing it for years (windows inside - displays anyhow). The goobs are just catching up. I'm very suprised the raptors were using time zones for anything at all, most systems surely would have been using UTC. It's got me puzzled why the dateline could have bought down every system. It'll be an interesting read if the report is ever made public.

Got your attention, just by the international date line, apparently the whole squadron lost all systems except the flight controls, luckily! Somebody was using the wrong calendar / time package :) >> 25 Years from development to deployment, the F-22 Raptor is the most advanced fighting machine in the air. It was no match for a computer glitch that left six of them high above the pacific ocean, deaf, dumb, and blind as they headed to their first deployment. So what happened? We turn to a man that's at home in the cockpit. Retired Air Force General Don Shepperd. Let me set the scene, Don. These F-22s, headed from the Air Force base in Hawaii to an Air Force base in Japan. They were approaching the international date line, pick it up from there. >> You got it right. You want everything to go right with the frontline fighter. $125, 135 Million a copy. The F-22 raptor is our frontline fighter, air defense, air superiority, and it can drop bombs. It is stealthy and fast. You want it to go right. On the international deployment to the pacific, it didn't. At the international date line, whoops. All systems dumped. When i say all systems I mean all systems, navigation, part of the communications, fuel systems, and they were -- they could have been in real trouble. They were with their tankers. The tankers -- tried to reset their systems. Couldn't get them reset. Tankers brought them back to Hawaii. This could have been real serious. Certainly could have been real serious if the weather had been bad. Turned out okay. Fixed in 48 hours. It was a computer glitch in the millions of lines of code; somebody made an error in a couple lines of the code and everything goes. >> This is almost like the feared Y2K problem that happened to these aircraft. We should point out, the computer problems in 2000. The computers absolutely went absolutely haywire and became useless? >> Absolutely. When you think of airplanes from the old days, with cables and that type of thing and connects between the sticks and the yokes and the controls -- not that way anymore. Everything is by computer. When your computers go the airplanes go. You have multiple systems. When they all dump at the same time, you can be in real trouble. Luckily this turned out okay. >> What would have happened if these brand-new $120 million F-22s had been going into battle? >> You would have been in real trouble in the middle of combat. The good thing is we found this out. Any time -- before, you know, before we get into combat with an airplane like this. Any time you introduce a new airplane, you are going to find glitches, and you are going to find things that go wrong. It happens in our civilian airliners. You don't hear much about it. These things absolutely happen. And luckily had time we found out about it before combat. We got it fixed with tiger teams in about 48 hours and the airplanes were flying again, and completed the deployment. This could have been real serious in combat. >> You had these advanced air -- not just superiority but air supremacy fighters in there, up there in the air, above the Pacific Ocean, not much more sophisticated than a Cessna 152 with a jet engine? >> You got it. They are on a 15-hour flight from Hawaii to Okinawa. When all their systems dumped, they needed help. Had they gotten separated from their tankers or weather gotten bad they had no reference and no communications or navigation. They would have turned around and could have found the Hawaiian Islands. If the weather had been bad on approach there could have been real trouble. You get refueling from your tankers and you don't run -- you don't get yourself where you run out of fuel.

lol another one. http://www.spikedhumor.com/articles/83664/Best_Anti_tank_Video.html

Heres' my guesses.

Do a search and you shall see. Here's a jamming 101 link for those who care. http://www.myaoc.org/EWEB/dynamicpage.aspx?webcode=GoldCrows_EWTutorial1

"BACKGROUND OF THE INVENTION In modern radar electronic warfare, a variety of counter-measures are used by hostile or enemy targets to avoid detection and/or deny range information, the distance between the aircraft and the target. For example, a pilot of an enemy aircraft with an on-board or escort ECM system wishes to avoid being prey to a missile by denying range for missile launch envelope calculation by another radar. A typical radar ECM is the noise jammer which conventionally broadcasts random in-band electronic energy to overcome for a period of time the ability of a victim radar system to detect and obtain range measurements of, or range on, the target being protected by the noise. Methods have been devised to overcome this kind of jamming, as for example, the polarization canceller. Recently, rapidly blinking and polarization agile noise jamming ECM techniques have been developed. Blinking jamming results when the enemy jammer periodically broadcasts powerful noise energy to defeat conventional polarization canceller ECCM techniques with rapid blink rates, because as the radar system's receive polarization adjusts to the jamming noise, the noise disappears. In polarization agile noise, the enemy ECM system switches rapidly between different polarizations of antennas. Conventional Polarization canceller ECCM for noise jamming fails for this jamming technique as well, when it is too rapidly agile, because as the radar system becomes accustomed to one polarization, another polarization is transmitted by the hostile target. "

http://freepatentsonline.com/5311192.html I think those who use blinking are infringing on this patent! :)

lol see what trouble you've started :megalol:

lol yes you can, it"ll just cost you big dollars to change the source code :P

http://www.defenseindustrydaily.com/2006/07/bae-wins-14b-order-for-aircraft-irdefense-systems/index.php I doubt that it's been fitted yet to the whole fleet.

yeah? i thought the AN/ALQ-144 is an IR jammer only (always on NO BLINKING ehehe)

Yeah that's the most annoying thing when ppl use it on your own side! It's the only time when blue on blue is cool :)

or better warning systems fitted. I think the Cobra's have missile warning detectors.

Fighters generally use Self Screening jamming in 2 forms,either noise or deception: 1. Noise jamming (modeled in Lockon?): a.) Spot noise, jam the current frequency the radar is operating over. b.) Barrage noise: jam the whole frequency band both shouldn't work if the jammer is toggled on and off, you'll just be highlighting your position in case the pilot was having a coffee and didn't see your track pop up on the screen. You should be able to lock onto the bearing (noise) and fire a HOJ shot. 2. Deceptive Jamming (assume not modeled in Lockon) a.) Basically the jammer tries to spoof the receiving radars tracking by giving false returns in range, bearing or doppler. Thus pulling the track the pilot will see on his screen of the actual position of the tgt in the end causing track to be dropped and the whole process starting again. So by blinking the jammer it's kind of like 2, your denying the correct tracking of the tgt, it's there for a second but then drops so you can"t hook it. Modern radars will counter the jamming by jumping frequencies (and many other ECCM techniques) so the ecm unit can't detect when it's being scanned and give false returns. But if you can narrow your scan and continue to track all he's doing is denying u that loussy long range 120 shot that will miss anyway! So you have a counter, you can still track the guy and position for the shot. As GG said just track them and fire when your in burn through range for a noise jammer. In summary if I'm not wrong, which I probably am :), ED has modeled noise jamming with the ECCM technique to counter it being burn through and HOJ so all should be fair, but some cleaver pilots have determined they can turn it into a deceptive jammer of some sorts, but the counter technique is to just track the guy until the burn through range for a noise jammer and fire. Hopefully fixing the 120s pk in normal and HOJ will stop most people from using the jammer for more than a second or so. ps if you want a very good book get Airbone Pulsed Doppler Radar, covers monopulse, phased arrays both types, ECM and ECCM. It's understandable and you can skip over the math if you want and still get the jist of it.

Well they're not being popped when it counts!

There is no "may" about it, they definetly don't work this way :D

Do the have missle launch warning systems fitted or is the ALQ-144 suppose to warn the crew as well? The don't appear to be performing any evasive maneuvers.

I was trying to say if the noise jammer is off as much as it is on, then if you hook the tgt in STT or a narrow tws scan you should be getting plenty of good returns from it when the jammer is off for the radar to track it, with position ambiguity granted, but it shouldn't be enough to block you firing with a pretty good PK.

Yeah but no but yeah but :) it shouldn't work - the searching radar would be getting plenty of good returns from you while your turning the thing on and off!! Might as well leave it off. It would probably look like a nice big strobe on the display pointing to the track saying shoot me!

Why can't the HOJ missiles re-acquire the blinking jammers?

just search on youtube for aim-120, there's a nice compilation of launches (first hit in the search).

The F111 was an offensive platform, it was selected by the RAAF to say we can reach out if necessary and strike any where north of us if required. The same can probably be achieved with JSF and long range stand off missiles but obviously the F-22 in most peoples eyes is a far more threatening that the JSF. Bottom line the SU-30MKI must be a great platform to have so many ex RAAF Air Marshalls and analysis buffoons scared out of their wits ... they just don't believe a JSF can make it through the Sukhoi defenses to hit the tgts. Even with Link16 and Wedgetail. an SU-30MKI vs a F15C would make great match up in Lockon with all things modeled well. :) or maybe a F/A-18F v Mig35 would be nicer than the old F18C v Mig29 combo.

its back a couple of pages.
