The NEBO-M can feed the data to the flap lid, and that can guide the missile, and the terminal phase it illuminate the target + collect the data from missile + command the missile to the target with the information from the NEBO-M and big bird.

The radar in the missile have better characteristic in the last ten km compared to the flap lid used as radar illuminator .

what do you mean "Radar in the missile" ?

and since we all know both SAGG and TVM are offshoots from SARH, it definitely needs a radar that work in the SAME band as what the seeker use to provide illumination.

All missile has S-400 a passive radar in the nose, few has active radar as well.

The illuminator is the flap lid.

TVM guided missiles are like a combination of command guided and SARH guided missiles... so they have a nose mounted radar antenna, but receive the signal reflected from the target aircraft directed by the engagement or the acquisition radar, or an emitting target using a jammer.

So, if the F-35 is 200km away, then the Flap Lid radar can't see it, but if it receive the coordinates from a big bird/nebo-m then it can steer command the missile toward the target.
If the radar illuminate the target ,then the missile seeker will see it in the last 2.5 km, means if the NEBO-M can pinpoint the target into a km big box then the missile can found its target with the illumination of the flap lid.

The Flap lid can receive the data from the missile, and its can lead the other missiles to the precise position.

If the missile has active seeker, then it can see the target from 20km ( if everything is equal).
Means it can feed back the data to other missiles, back to the main radar, or can illuminate the target for other missiles/radars.

China will soon start placing their S-400 in Tibet. This means India will no longer be able to operate their Su-30MKI or any other fighter aircraft from their forward bases close to the border with China

uh no. The 48N6 or 5V55 still use a slotted planar array Or parabolic.

SAM 48Н6Е3 and 48Н6Е2 with a range of 250 km and 200 km have the same layout and semi-active homing, working on targets with speeds up to 4800 m/s and 2,800 m/s respectively, and upgraded adaptive combat gear, specially designed to increase the efficiency of destruction of ballistic targets.

Rocket 48Н6Е3, 48Н6Е2 (Fig.3) single-stage solid propellant engine, made by the normal aerodynamic scheme, start - vertical ejection from the transport-launch containers.

I remember it was first reported as a done contract, then in some media it said it was a memorandum of understanding and that talks were ongoing to define everything. To this day I haven't seen any news about timetable of deliveries, cost of contract etc. Have some news slipped past me?

Your point being ?

Im talking about MISSILE SEEKER antenna here not other stuff.

and clearly this is not Phased array or sort of it.

Will India deploy its S 400 to do the same to China ? That's another scenario. My point was only about China using S 400 to seal Indian airspace.

GarryB wrote:Of course it is not... a dish type assembly is all it needs to look for the emitted radar signal reflected from the target...

There is no need to scan with an active signal to find the target... just move the dish until you get a strong return and that is where the target is.

miketheterrible wrote:Depends on the missile.

They already operate such guidance systems. 9M96 for instance has an active radar system.

Many long range missiles don't benefit that much from it because low power output that can be provided from the APU means less power to do much and possibly easier to jam anyway. Having a very powerful ground based system tracking enemy aircraft and providing the guidance for the missile, is a very good structure. Especially in heavy EW environment.
