Pakistan's Airborne Early Warning and Control Aircrafts

[SQ8]

the ZDK do not have an AESA radar.
what about the EriEye,, is that also PESA??

ZDK has a hybrid.. AESA scanning in the vertical..which provides something of a 90 degree cone.. that is rotated 360 by the disk.
Erieye is an AESA system.

Arsalan,

How did you miss that? Man, the last few pages have been precisely on this discussion that both PAF's AWACs platforms are AESA.

ZDK 03 has the arrays in rotating dome, whereas Erieye has it in static housing. However, the Erieye has 60 degree field view, from perpendicular to either side. We don't know yet how much the ZDK-03 has, but Sapper last stated it might be 75 degrees either side. So keep checking. I actually find this thread very useful.

Dear,

A bit of correction required, since presented information is being attributed to me.

1. Erieye uses AESA 75 deg on either side of perpendicular, meaning 75+75 = 150 deg on one side, 150 deg on the otherside, totaling 300 degree of total instantaneous coverage on both sides. Information is extracted from Erieye Brochures, and is confirmed since it is based on manufacturer's claims.

2. ZDK-03 must have atleast 60 deg on either side of perpendicular, meaning 120 deg cone, atleast. Information is a guess from my side as Chinese KJ2000 and KJ200 have AESA with atleast the same specs, but it could be higher. I have no hard evidence to support this because Chinese AESA have not been formally presented in any brochures etc. I am still looking for evidences regarding this, but so far no hard evidence.

Regards,
Sapper

This is a very informative and researchers' thread.

Yes, that is why i mentioned you. Good info. Let's hope the ZDK-03 specs remain shrouded in mystery. Keeping your enemy guessing in this electronic warfare age, is of utmost importance.

I wish there was a way in which we could tag other members to call them in on specific posts.....akin to the Facebook tagging concept.

Maybe Webby can come up with an idea?

Can same be said for Elta C-295 ?

Nope.. AESA scanning both in vertical and horizontal.. around the estimate sapper has made of 150-160 cone..
Less of a gap in the radar picture..

Look great, I am curious the tail's wings in the backside, what does that mean?

May be its for submarine search

Nope.. nothing do with submarines or even sensors.
If the two additional vertical stabs are what is being pointed out then these are there to cancel out aerodynamic forces that occur due to the addition of the external attachment known as the rotating radome.

Those extra vertical stabilizers are added as the radar mounted on the top of the fuselage disturbs the aerodynamics of the aircraft and one vertical stabilizer is not sufficient

Other aircraft with such empennages are

Antonov An-225

Shuttle Carrier Aircraft

Interesting, I see. Similarly to other AWACS with different designs of vertical stability or Elevators.

To me, these additional Vertical stability in ZDK (Pakistani AWACs) design is not accurate or weird, maybe engineers know the best.

Even the Mexican Air Force Embraer R-99 Has it. It does not even have a rotating radar. They add extra stability

These carry a high ammount of antennas, arrays and sensoring equipment on the tail. Alot of Antennas.

Take a look at the Saab Erieye...
It just depends on the platform and the placement of sensors which cause the aerodynamic anomalies.
