Could this detect the b2?

>>63878418 (OP)
>extremely long wavelength
No.

>it gets destroyed by a B2
>you now know there is a B2 there
I guess?

>>63878421
I don't get it, it is a tall tower not really that long

>>63878430
An antenna should be one quarter of the wavelength long for physics reasons I have forgotten in the 20 years since trade school.
this means the wavelength from that would be so huge it couldn't see anything with a small return but could see things with a big return from extreme ranges.

Why are you making this thread again? All real discussion happened last thread you made with that identical OP image.

>>63878448
We are actually completely different people

Depends on the kind of radiation its shooting it at.
Early warning give you a certaib idea of were the bomber is then you shoot then with Heat seeking missiles

>>63878454
Is that sort of thing like how nogs believe that the person 15 minutes from now on is a completely different person?

>>63878454

Well now you can go read that thread and close this tab.

>using early warning radar to guide heat seekers
I hate that thirdies have filled /k/ and are being retarded all over the place.
At least the COD kiddies wanted to learn.

>>63878500
You can use 3 early warning radars to triangulate a position. All it takes is precise coordination. It can be precise down to the decameter level with 2.4ghz phased arrays at 200km

>>63878526
Ok lets say you EWR array has good targeting data, why the fuck are you launching a heat seeker that is lucky to see 10km instead of a radar guided missile which can engage as far as the rocket motor can take it.

>>63878548
I'm nta. Was just pointing out that direct RF sampling paired with completely digital signal analysis has opened many avenues that just weren't feasible with analog or hybrid setups

You don't even know how radar works and what are the differences between wave lengths you stupid fucking mongrel.

>>63878445
>should be one quarter of the wavelength long for physics reasons I have forgotten in the 20 years since trade school.
Ideally it would be exactly the wavelength you wanted to transmit or receive, but that's often impractical because it can mean a really fucking huge antenna. Any power of two division works, though not as well: half-wave, quarter-wave, eighth-, etc. Quarter wave is commonly used because it's a reasonable compromise between performance and practical size of the antenna.

If you just want to detect rough distance and direction, there should still be advantages to using longer wavelengths.

>>63878667
The problem with long wavelengths is they have trouble detecting small returns and the B-2 has the RCS of a bird.

>>63878630
>You don't even know how radar works and what are the differences between wave lengths you stupid fucking mongrel.
I dont need to know that only faggots and sailors know that

>>63878673
you mean short wavelengths?
With long wavelengths, the whole aircraft acts as a single radio body, ignoring its small details. It is short wavelengths that are affected by the small details in the body

>>63878418 (OP)
Isn't this for detecting submarines?

>>63878491
>Is that sort of thing like how nogs believe that the person 15 minutes from now on is a completely different person?
I don't think that's specific to them it's more a sub-85 IQ thing. Which covers the majority of the nog population granted but there are plenty of true genuine retards in this world who have extremely weak theory of mind and are incapable of serious abstract thinking, causality analysis etc. There is some copypasta image about it.

It's pretty hard for normal people though to understand that there are true unironic retards out there who aren't even "lying" per se when they get outrage over trying to hold them accountable for something they did awhile ago because that was some other person from awhile ago.

>>63878686
Its for detecting mole men

>>63878793
Read about Project Sanguine you clown

>>63878548
Because the long wave ewr radar can tell you there's a plane there, but not it's exact position; if the area on uncertainty is within those 10km, then it's close enough for the heatseeking head to home in on the exact location without being affected by stealth or jamming. The biggest problem with infraread seekers is actually that they can be defeated by clouds, so they are only guaranteed to be the best option for high flying supersonic targets - and the b2 is the former but not the latter.

Idk but lets jump out of the plane and land on top of it its literally such a god tier place to drop im gonna pick up a kar98 or something and blast about 10people before i even come down

>>63878418 (OP)
>detect
Probably. And that's about it. Its OTH eartly warning radar. Not search or track radar. It would show a small disturbance until the wheels are retracted after takeoff. Would you scramble interceptors westward if you detected 8 small birds in even intervals for 15 seconds in the general direction of Whiteman AFB +/-5 degrees and +/-1000km? Most likely it wouldn't even pass threshold for clutter to be fed into any processing or else you'd have to process thousands of birds.

>>63878421
Long wavelength radars would actually be better for detecting a B-2. They wouldn't get a missile lock, but they would be able to track it and guide interceptors to the area to engage.

>>63880100
Cold war tech is so cool

>>63878418 (OP)
no because it never worked properly, in 8 and 16MHz bands there was mututal interference between duga and civilian stations and the modernization to 4MHz band failed because of previously unknown auroral phenomena

>>63880166
damn straight.

Even if they could be spotted by powerful ground radar, interceptors would have no way of identifying the B-2.
Old-fashioned searchlights may be surprisingly useful in this regard, but something new would have to be invented, such as a laser, to illuminate the B-2's altitude.

>>63878418 (OP)
No. That station hasn't been operable since Chernobyl.
Google your retarded questions next time

>>63882498
laser range finders/lidars are a thing since lasers were invented.

>>63880166
I'm cold war tech and I'm pretty cool.

>>63882688
a super intelligence's super intelligence.

>>63878817
How about you reread about it? Elf stations for underwater communication is nothing new but how did you mistake that for detection?
Damn, there are so many tourists itt.

>>63878418 (OP)
I thought that Duga thing was just a made up location in Stalker.

>>63883436
It was originally going to be the Brain Scorcher, I think.

>>63878418 (OP)
If you made it tall enough, you could catch a B-2

>>63878418 (OP)
If it collided with it.

>>63883497
fpbp

>>63883368
Submarines are very hard to detect so you need something like ELF detection

>>63878491
Ok I'll bite: is this a thing? Ir a "thang"?

>>63883878
DAS RITE

>>63883436
The Duga radar is, in fact, very real.

How do you "aim" this thing? Like AESA? Or does it just blast off and you focus on a small part of it?

>>63888179
AESA and PESA are common and Russia has both, for those VHF/SW and high power radars AESA is common.
>Russia has difficulty making X/K band (IEEE) AESA radars with good processing power, that's a different niche compared to those OTH radars
