I mean there is a lot of metal in the antenna and reflector and magnitron feeder receiver etc. Then this should pertain to matterlegy as well. Then we apply paints and fluxes, then it should pertain to chemicals as well.
Bhai, Radar is not a communication device, unless you are an enemy who detects our location through Radar emissions. In that case, Radars work for enemy.
Its works like your eyes(passive sensors). Eyes are not communication devices, unless you are communicating with a girl...

A Radar is a science and engineering based device. We can talk about it in science terms. Let's focus on it:

Radar is designed to SEND radio frequency out and Interpret the frequencies that come back. This is ALL radars do.

Radar's transmitter, like human mouth, sends communication out in waves, not voice (or silent voice you can call it). When it hits an object in the air, it returns the waves with a pattern change.

Radar's ears that listen, like human ears, are the Receivers. They then interpret the returning waves and process a picture in dots (older radars), 1d, 2d and now 3d images. So that's it, it essentially talks and listens and processes a response and therefore, its a communication device, NO other purpose.

Now whether it uses "metal", or has "green color" on it, or its put on a truck, or made with Rare Earth materials, those are useless to discuss as we are discussing what is this device used for. Now how its built.

Just a caveat. Modern AESA can also double as communication system.

ok so now can we get the photos of the S400 site ?

of have they been permanently archived ?

Operational capability of this latest SAR based system will allow Pakistan military to cover major parts of Indian territory in real time and share that data in high resolution images back to the ground stations.

With a couple more Radar and SAR equipped Satellites, Pakistan will be in a position where it can guide it's own missiles to target from its own small constellation of around 3-5 Satellites. This series of Satellites will allow Pakistan to do its own imaging and analysis and not have to depend in BeiDou constellation 100%.

@Hakikat ve Hikmet @PAKISTANFOREVER @TAC @hussain0216 @PK781 Your opinion on this capability and development?

This is satellite actually cover Indian terrority? My impression was it was geo-stationary orbit above Pakistan.

This has been achieved a few years back with Chinese space intelligence. All of India, every inch of land and water is under their watch.
The problem is images are not allowed to be released, but it let's the Pakistani military to prepare.

Thanks man. This I didn't know. So basically radar + antenna system.

Exactly. Since the array is software controlled it can be programmed to do radar functions, comms or electronic attack, etc.

Adaptive array antennas..

@Waz sb

Why? I think it would be in Chinese interest to see India completely humiliated.

No, Foreign Minister Wang Yi is about to visit your home.

That is why it was launched. Hopefully, we'll send a few more and create a constellation of our own satellites. Totally independent of requiring any GPS guidance or live imaging needs from China or other nations.

That's actually inaccurate. The data sharing is part of every radar whether from 1980's or today. That's just a radar function.

If every radar can do Comms, Jamming, EW, you won't need near 3-4 radars in every EW or AD system. You'd just use one radar like a multi-role platform.

The radar for search is designed to search and perform that function. It can communicate with other assets and share communication about its search data. The radar designed for "target designation" performs just that function. Believe it or not, it's interface is entirely different than a "search" radar. Next is weapon control or missile guidance radar, that's different and only does that function.

Lastly, the electronic attack Radars are different and their purpose is to use frequency hoping and disruption. It's interface is different.

When addressing such critical issues, kindly post sources or write that you are writing this with experience. I am writing this with some background, seen a few AD / EW systems.

You know instead of writing with such certainty you could have just done a bit of research. But sure:

EA/EP function:

AN/APG-81 Active Electronically Scanned Array (AESA) | Northrop Grumman

The Northrop Grumman AN/APG-81 active electronically scanned array (AESA) fire control radar is the latest and most capable AESA in the world and acts as the cornerstone to the F-35 Lightning II's advanced sensor suite.

AESA can basically be used as a multifunction array. Obviously the limiting factor of the use case would be the band and the software behind it.

Next time try not to be obnoxious. You can ask the same question politely.

Now are in dealing with Pakistani style ego and sadly, arrogance also.
What is new here that I didn't already cover?

First of all, throwing this term "AESA" is silly. Why? Radars have existed before the WWII. Their role hasn't changed much. Only the generations of tech has. Back in the 80's and 90's, the radars would still be configured to do everything an AESA does today.

AESA just does it faster and compact. Why? Because the computing power has increased 10 folds compared to 1980's. Google Moor's law to educate yourself on what I mean here and may be you can put some pieces together. Otherwise, good luck.

Do you understand what " data" a radar communicates? AESA or NO AESA? The data is the same from the 50's, 60's or in 1980's. Radar is a communication device. It speaks with waves it sends, it listens with waves it gets back. The resulting picture, is the DATA on the screen. It displays that data on monitors, in the form of pictures or shares it to some other location or through various mediums like Satellites or AEW planes, etc. That's communication. So what is new in it?

The PAF's radars were providing "data" to various sectors back in 1980's. Today they just replaced many older one's with AESA technology. Same functions.

Now coming onto APG-81, that's a fire control radar. It will work as a fire control radar. What's the point you are trying to make?
