AMCA - Advanced Medium Combat Aircraft

[randombully]

CAN? Ofcourse it can. And it has been developed aready it seems. Different makers make products in different shape, form, quality but the underlying science & elements are same.

A 5+gen jet is actualy supposed to have spherical coverage of RF & EO sensors & hence AFAIK all 5gen jets have X, L & some other band antennas for different functions. Check following past post :

A collage of diagrams of EW antennas, GPS, SATCOM, Radar altimeter, TACAN, RWR, IFF, VHF/UHF, L-band, data link (IFDL/MADL).

The diagrams say "preliminary" so final positions may change.




The following is collage of F-22's & F-35's sensors & antennas:

Pic mentions SDR, i'm assuming it means software defining radio and I'm talking about L band radar with many antennas that can be used to "detect" Stealth tragets from long distance( more than100km) like ruskies are doing in su 57.

"A pic is not available yet but the diagram shows L-band antenna on tail, so it is obvious that frontal hemisphere sectors will also have it, most probably on the leading edge slats."

Hope it's true, would be pretty useful.
Specially in himalayas where ground based long Range l band radars will struggle due to mountains an smaller but airborne L band radar inside a stealth fighter itself will give us a big edge.


Though power generation could be a problem to incroporate it in AMCA, don't know if f414 will be able to generate enough power.

And so far, only su 57 seems to have this.
Neither f22, f35, j20 seems to have an L band radar.

Can AMCA have L band radars and other asymmetric features ruskies have put in su 57.
Like best of both world, stealth similar to f35/j 35 and also asymmetric anti stealth features.
Or are we going completely western style route?

It can, but frankly I don't even think L band radars provide any meaningful advantage that a ground based SAM radar couldn't using its own longer wavelength radar bands.

L band can only help you detect a stealth target, but you will need a short wavelength, high energy band like X band to actually engage the target.

You will almost always use the higher energy bands like X band to achieve a weapons grade lock on a target instead of the L band.

Yeah I know, but you can't always depend on ground based L band radars especially in mountains of himalayas, L band and x band long range radars struggle there.
And Just knowing that there is a target 100's of km away In a certain direction with an accuracy of few km's is a big advantage.

Well, I never googled which engine generates how much electricity. ut if Rafale's M-88 can give electricity for its inbuilt SPECTRA suite & other atennas then let's hope that F-414 should also be able to support AMCA's suite. Also, i think GaN based trancievers are being developed which have much lesser power requirement.

IDK about J-20 but F-22 & F-35 definitely have it on spine & belly ahead of bay doors. You didn't see the labeled diagram properly

Pretty sure those on f22 and f35 are not L band radars atleast not in the same sense of the L band radar on su 57.
First those on f22 and f35 are too small,
second You need those L band aesa antennas to face in same direction As your x band aesa radar to detect enemy stealth fighter jets at long distance.
All L band antennas are not radar, L band has many other uses in fighter jets like IFF, EW, SATCOM, situational awareness, secure communication etc
