If you are not ready to do high school math, then you should not mess with the Doppler effect and blob algorithm. Specially when they are completely out of the subject.

Wrong my friend. Each radar designed has its own P minimum. Don't bluff me about this.  

 

If you have an opinion about this article and the general subject around it, feel free to share it with us. Without unneeded complex word or concept.

 I shared it with you. You did not understand concept and you tried to run a bluff. It didn't work.

about the little math, it point out that even on the X-band, there is way to pick a LO at long range, trough the improvement of captor,software, emission power etc.

 Again without seeking to offend anyone,  you don't know what you are talking about. There comes a practical peak power throughput limit where sidelobe noise interferes with signal gain at the receiver..There is also clocking which you ignore. That is 80% of the signal processing game to which you re3fer inaccu

rately.

Radar basics...

But a stronger emission have the annoying side effect of virtually placing a huge flashing neon sign on your ship that says: "LOOK AT ME! I'M HERE! SHOOT ME, SHOOT ME!!"

Hello Bluewing12

I think whe should stay concervative, after all, its all top secret technology. And there his alot of disinformation. 

IRST and other focused IR detection device have a limited capacity to detect a plane, LO or not. Because it cant cover a large portion of the sky. But Once a plane is approximatively located. It does enhance the capacity to track a LO plane, specially at high altitude where the atmosphere is less dense. Keep in mind that when LO plane like the raptor lunch a missile, he have to open his bay. Greatly reducing his RCS.

I don't think the focused IR detection technology is fully mature. But its clearly a "must have" feature.

I have a quick anecdote about disinformation:

I dont remember exacly the year but it was around 1993, I was very exited because whe where lucky enought tho have a F-117 at the Quebec International Airshow. I had the oportunity to talk to the pilot. I asked how fast the plane was. of course he could not answer. Like a 13 kid, I quickly told him everything I knowed about my favorite plane of the time: the SR-71 Black bird, ya i was young lol. And The Pilot told me that the F-117 was even faster then the SR-71. After a quick look on the plane, i turn to him and said: its not possible, the plane is not aerodinamic enought! the pilot smiled and said "Are you sure?" I looked the plane again and start to wounder what i didnt know.

American Pilot: 1

Little Kid:          0

as you say:

Cheers
 

You answer:

 

OK...  Look the link you send to me

link

Look all equation, and you will see that transmitted power(Pt) is always a multiplicator.

Software:

Look under the topic Angular resolution and range resolution, Paragraph 8

Improving the software will improve the capacity to discriminate noise and target.

whatever if it use a "Dopplerized Blob algorithm clocked Signal processing" that you like so much or a more conventional (and less Fictional) Barker Code.

 

In regard of the link you send me, my statement was correct.

 

The debate about how work radar is not exactly what whe are talking about here. This topic is about the article: Radar versus Stealth: Passive Radar and the Future of U.S. Military Power.

 

So please, stick to the subject. or create another topic about your "Dopplerized Blob algorithm clocked Signal processing"

 

If you are not ready to do high school math, then you should not mess with the Doppler effect and blob algorithm. Specially when they are completely out of the subject.

Wrong my friend. Each radar designed has its own P minimum. Don't bluff me about this.  

Humm ok.... What happen if the radar was not designed and have a N maximum? Seriously...  P minimum, out of its context it could mean anything. But you probably mean transmitted power(Pt)  minimum

 

And what it have to do with high school math?

And why are you out of the subject again?

 

I said:

about the little math, it point out that even on the X-band, there is way to pick a LO at long range, trough the improvement of captor,software, emission power etc.

 Again without seeking to offend anyone,  you don't know what you are talking about. There comes a practical peak power throughput limit where side-lobe noise interferes with signal gain at the receiver..There is also clocking which you ignore. That is 80% of the signal processing game to which you re3fer inaccurately.

Of course it is. Its quantum limited. Temember when I asked you if you knew what a light wave was?

You read i

Argue with the author. Its a  device to capture a return. He calls it a captor. Its technically correct when you talk about LIGHT.. 

 in contemp technology electrons in radar are regarded as a related lightwave technology - they emit light and carry current.. 

N maximum was sarcastic way to point out that P minimum don't mean that much out of its context.

Its a standard term in the radar equation.  You;didn't know it.

 

The use of the word Captor was my mistake. The author don't use Captor at all. He use the word receiver... so i guess you didn't fully read his artice. And by the way, Radar don't use light. it use electron: RAdio Detection And Ranging

I don't fully and deeply understand how Radar works, and i don't pretend to be an expert. But i clearly see that you are not an expert too.
 

Now that whe have finish about that, can whe go back to the subject? Anyone else have a opinion about the Radar versus Stealth: Passive Radar and the Future of U.S. Military Power. ?

Don't confound wavelenght and lightwave. If by "related lightwave technology" you mean that light and Radio are in electromagnetic spectrum, ya its true. but dont forget Radar are not designed to "see" light and if it emit something else then radio its a very undesired sideffect. Detecting radio, IR, visible light, X-ray amd gamma ray imply a completly different set of technology.

I'm not  AESA radar systems are regarded as a discrete weapons solution.  thats because of the way that the radar can be managed.
