And interferometry rather than a dish.
“The SAM-N-6b used a solid-fueled rocket booster and a Bendix ramjet for sustained flight. Talos was guided to its target by beam-riding, and used semi-active pulse-radar guidance for terminal homing. The characteristical small antennas around the nose of the Talos missile were the receivers for the SARH system. Talos missiles without these antennas were either training rounds, or nuclear armed missiles, which didn’t use terminal homing. “
Dude, you must be a bigger idiot than I thought. Read small. And guess what small does to radar receiving range.
Dude. Wavelength. Seriously.
Dude you don’t know wavelengths when it hits you. You’re trying too hard to be a fool. Seriously, read up on it.
*Since this thread is busted anyway* I too have heard this. But I allways wonderd how it works. My damn microwave shuts off as soon as I open the screen/hatch 🙂
Those Serbian engineers surely were no fools…
They are likely to have taken out the magnetrons from the ovens.
Yeah, I missed that Talos bit. I guess he didn’t know it was a 33 foot long SAM that didn’t even have a seeker behind the cone. 😉
Dude, the missile uses SARH for terminal guidance. Its only a beam rider in its midphase.
OMG!, LOL!
BTW, what are the main differences between Yakhont and BrahMos?…I though it was the inertial platform, but at least, Yakhont (on silo and ground mobile launched version, that’s Bastion) has waypoint (seven) capability, althorough no (AFAIK) land attack capability…don’t know if naval BrahMos have that through…
Physically rather big. The Yakhont uses a duct underneath the airframe to breathe, while the Brahmos uses an inlet style of intake on the nose.
The nose style of intake allows the missile to be more compact, but it has a catch on its own, for the same reason why jet fighters don’t use nose inlets anymore (e.g. MiG-21). That’s because it can potentially limit the size of the seeker array and components. Note, its also a factor in the obsolescence of the Talos.
Its got to be said that the Microwave Oven Maintainance Fundamentals course is fascinating and I’ll forever wonder about the stealth properties of the lowly Samsung unit that nestles in my kitchen from this day on..
I am just wondering what relevance, Crobato, the technology you are describing so accurately has to do with antiship missiles?.
I was trying to explain to that dunce sfool over there that magnetic style RAM isn’t likely to be used on supersonic missiles due to heat magnetization. That refers to forms of painted and elastic applications that use ferric or ferrofluidic materials mixed in. With platforms that will be faced with an abundance of heat, it would be better to use dielectric style RAM, of which most types would use some form of reentrant echoes for canceling. The microwave oven is an example of such. With subsonic antiship missiles you can get away applying thin layers of magnetic style RAM, but for supersonic designs, you’re going to need layered dielectric RAM that has layers of screens and matrices using Jaumann principles. Since thickness is a bother, such designs cannot be added ad hoc to an existing design, the stealth supersonic missile is one that has to be designed from scratch from the bottom up to incorporate structural dielectric RAM.
I have not seen such a helicopter in the PLAAF. The only US made helo is the Blackhawk, which is still operating with them and even served in the Sichuan earthquake rescue efforts.
The PLA (Army) has their own helicopter arm separate from the PLAAF and none of them seems to use anything like you mentioned. Perhaps with the private enterprises.
Screens act as REFLECTORS. How the hell do you think radio telescopes work? They’d be pretty damn useless if their REFLECTING antenna ABSORBED the signal they were trying to magnify.
This certifies you as a complete and utter MORON.
Look at a screen. It PARTIALLY reflects and it PARTIALLY lets through.
If you want to act as a pure reflector you won’t use a friggin SCREEN at all. You would use a tint on the glass or you would just make it opaque with a metal plate.
BUT YOU WON’T USE A SCREEN.
In addition to that, you won’t need to use a separate layer of reflection (the tinted window glass) and you won’t have a friggin CAVITY in between them.
You still don’t understand what a friggin Salisbury screen is.
Screen partially reflects the microwave. Lets some through. This will be the first reflected wavelength.
Those that pass through reflects on the second surface. That will be the second reflected wavelength. This will pass through the screen and meet up with the first.
Cavity is set about 1/4th of the wavelength. That means the second reflection will be out of phase with the first. When two waves of the same frequency but out of phase meets, this causes cancellation of the two microwaves.
Kapisch?
Why can’t you have the microwaves bounce all over inside the oven? Have you ever wondered that this may cause a sharp rise in the intensity, and that cooking requires that everything has to be heated on a constant temperature?
What makes you even more idiotic is your comparison to a radio telescope, which is deliberately shaped to focus the radio waves to a point. There is NO SUCH THING and absolutely NO POINT TO IT on a microwave oven. You want the item to be set on a constant exposure rate.
Guess which company invented the microwave oven. That’s right. It was Raytheon.
i said we hope to fly su-27 and mirage 2000 not we flew them, as we were planning to get them prior to 1991
thanks
Actually buying Russian and French stuff is more likely to make the US unhappy.
BY 2011 THERE WILL BE A NEW AIRFORCE WITH strike capability in form of fighters (jet) in at least 3 squadrons, you may not know that there are few airframes left from the old iraqi airforce in the form of:
1. handful of chinese F-7B i dont know their condition
2. one or two su-25’s
3. a number of pc-9’s that escaped being destroyedthere were talks with france on gazelles but the french offered 2nd hand ones or older versions thatn the IrAF hoped
i know iraq has 36 f-16’s on orded my guess is it will NOT happen since the americans are pulling out completely.
the IrAF will eventully go back to its roots flying su-27 and mirage 2000 in fighter role and i dont know what in the strike role,,,,i recommend talking to the british on ex-RAF tornados.
Order of F-16s has no bearing on the American presence or pull out. The issue is completely independent. The US wants you to buy the F-16s, after all its time they stand to make money with it.
Bogus.
How many F-16s have been lost in the last 20+ years due to the engine conking out?
Well a few years ago, a ROKAF F-16 did, and it was just one of a long list. The F-16 fleet was grounded as a result for inspections. And as a result, ROKAF also requested that their F-15 buy would have GE instead of PW engines.
One of the ROCAF F-16 crashes are also blamed on the engine.
Nice. I see a PL-12 there and the wide angle HUD they’re using.
Looks like they’re only assigning 4 crew people for one aircraft now, compared to eight before.
Quick search can reveal that the oven door is a Faraday cage.
The oven itself is a Faraday cage. The door itself is either a Salisbury or Jaumann screen. Don’t bother to instruct what a Faraday cage is to a mental dunce like sferrin.
You really are a glutton for punishment aren’t you? “It reflects back in and back out in a recursive fashion till the wave runs out of energy or cancels themselves out.” That’s not what’s happening on a microwave oven door, nor is it what’s happening on the F-117 intake screens. Like I said, go read about it.
You are the glutton for embarrassment. Continue to advocate from a position of IGNORANCE you fool. You are always acting arrogantly and yet from a position of sheer inferiority of technical knowledge. You’re like that braggart Republican congressman who is advocating mandatorily teaching the Ten Commandments on schools but when asked to name the Commandments, couldn’t name them.
GO READ ABOUT IT. Don’t show me Google or Yahoo, when you actually DON’T EVEN READ or couldn’t even comprehend the principles behind stuff you post. All you know is this plane has this, this plane has that. That sounds like a boy who doesn’t know crap.
Yes, what I said happens exactly on a microwave door. The door consists of the outer window which is radar reflective, a resonating cavity in the middle about a quarter wavelength and the screen on the inner side that lets some waves through and others to reflect out. The screens lets the waves go through, bounces on the window pane, which reflects back on the screen, which in turn reflects back to the window again, creating a resonating effect. Some of the reflected wave come out of the screen, these would cancel out the waves that directly reflected from the screen itself.
Go read what Salisbury and Jaumann screens are. Yes, screens in the F-117, heck, all screens work in the same principle of forcing recursive echoes. Besides the screens there is also an inner layer beyond the screen that does radar reflection back to the screens.
Just keep typing, this is entertaining stuff. 😀 Do you know the difference between “reflect” and “absorb”? There is no RAM in a microwave oven door. It has a metal screen that REFLECTS the microwaves back into the oven. That’s why nothing gets out. Go google it if you don’t believe it.
You’re really full of BS. Why don’t you actually take your own advice.
That’s exactly what happens in dielectric RAM. It reflects back in and back out in a recursive fashion till the wave runs out of energy or cancels themselves out. THAT IS STILL RAM by the most used definition of it. The screens on ceramic, carbon fiber and composite matrices all use the same principle.
If you are dealing with elastic forms of RAM, you’re dealing with something with magnetic particles embedded on it. That’s placed under Magnetic RAM.

Microwave absorption is the process of absorbing microwave/radar energy at discrete and broadband frequencies by converting the microwave/radar energy into heat. This is achieved by magnetizing an elastomeric material by filling it with a magnetic alloy such as carbonyl iron or ferrite.
