Which AESA radar fits better the JF-17 Block 3?

[Arsalan]

Strange how the opening article is relating KLJ-7A radar to the radar of F35 and even F22, even calling them technologically at almost the same level. However then he goes on to mention the detection range of 3 Sq. meter targets at 80 - 100 Km. Am i missing something here or is it the author who have no idea what he is talking about. F22 radar can detect 1 sq. meter target at ranges in excess of 200 Km and for 3 sq. meter it will be much more.

we had such indications, i am curious where will be the additional hard point, under the air intake is my guess
it will also mean no major change in air frame which was expected i guess

Sir @Arsalan has answered one part, i would like to answer other part.

There will be some change + wings will be more strengthened to carry more heavy munition and more A-to-A missiles BUT number of hardpoints will remain same & more composite material will be used.

I talked to my relative who is engineer in Pakistan Air Force he says AESA will be Chinese and JF-17 BLOCK III will have 8 hard points

u r partially right

Not in a mood to give a lenghty answer but i can simplify .

KLJ-7A for Next Blocks while the under development AESA radar with air cooling system must be given to Block 1 and 2 after some years as mid life upgrade kit

Sir I have been promised JF-17 flying like mad very very soon. I am still waiting...

Earlier reports said JF-17B should be available in April. It's already April...

u were promised by me . I didnt say for jf-17b...i said block 2 single seater is very soon going to give a hell of a show

Hazrat is the wiki leaks of PDF. the info "MUST" be taken with a pinch of salt!!

I would like to say Vixen 1000E has one advantage over the KLJ7-A and that is its ability to scan a wider area at extreme angles surely gives it an edge over KLJ.

mate this capability is deadly against any thing equipped with pulse Doppler radar (be it aircrafts, air to air or surface to air missiles ).as pulse Doppler radar has a blind spot it can't detect an object which is not moving toward or away from it. means roughly speaking if your aircraft is flying at exactly 90 degree angle from the enemies missile or aircraft they can't see you but with this radar you can as yours is on the swash plate and unlike theirs is an aesa
i wish Chinese incorporate the swash plate in their aesa too.

Sorry, I didn't make it clear. I understand that JF-17B is separate from the Block 2 single seater show. I was just saying time seems to be moving too slow and there are too many promises that haven't materialized yet...

Here is the real deal...

A body's RCS is composed of two things...

1- The body's shape.
2- The ability of the radar to detect and process whatever emanations that came off the body.

What this mean -- and it is going to be a shocker -- is that you can have the same body producing different RCS values BECAUSE OF ITEM 2.

The only body -- according to the laws of physics -- that can have a constant RCS regardless of item 2 is the sphere and that is why the sphere is used as a calibration shape.

https://en.wikipedia.org/wiki/Lincoln_Calibration_Sphere_1

The Lincoln Calibration Sphere 1, or LCS-1, is a large aluminium sphere in Earth orbit since 6 May 1965. It is the oldest spacecraft still in use, having lasted for over 50 years. It was launched along with the Lincoln Experimental Satellite-2 on a Titan IIIA. It is technically the oldest operational spacecraft, but it has no power supply or fuel; it is merely a metal sphere. It has been used for radar calibration since its launch. It was built by Rohr. Corp. for the MIT Lincoln Laboratory.

So just because the AESA radar in the F-22 can detect a 1m2 complex target at 200 km, that does not mean another AESA with the same array size can perform identical to the F-22 for the same complex target. It is both hardware and software that is in item 2. The base technology can be the same for both AESA radars, but the quality manufacturing of hardware and software is likely to be different, hence, different results.

promises such as? btw the promise i made is yet to come..next month dear

swash plate of vixen requires futher more power which (i may be most probably wrong) cant be afforded due to engine capability restriction

The promise of all those news feeds that claimed JF-17B in April

I say the moment AESA is ready for BLOCK I and BLOCK II fit in them

The promise of all those news feeds that claimed JF-17B in April

JF-17 B is coming in next few months it will arrive and this is just 7th April so even April is not over yet

@MastanKhan gave a good lecture on cons of introducing new tech suddenly to mai fleet earlier....it would take our pilots yearsss to master that tech...i say block 3 for now wih AESA while block 1 and 2 after 2021

Thank you sir for your detailed reply, informative as always.

However i was not arguing in favor of what was said in the opening article. Actually, i found that strange how someone is comparing KLJ-7A with the radar of F22or F35, they are no match for one another as far as i can tell from the pretty basic data available. I surely do not know all the details so i cannot talk about those but the very basic things, like even the detection range is MILES apart for KLJ-7A and AN/APG-77.

Anyway, i will come to what is actually important for me now, what do you think about this new radar for JF-17? What are your views about KLJ-7A. How good it is and how well will you rate it. Some data is already given about it, rest you may be able to assume/educated guess based on your experience and knowledge. Will love to pick your brain regarding this possible future radar of our main fighter, that is likely to be KLJ-7A

I am also excited specially as I came to know that it could carry dual racks on both sides for BVR. I think Pakistan should induct 50 of these also by than BLOCK III will also be ready
