Pakistan's Airborne Early Warning and Control Aircrafts

[graphican]

When PAF was repairing the Saab AWACS, they learned new European standard techniques of riveting and assorted engineering. I wonder if this went in to the JF-17 manufacturing as well. This could perhaps give a clue to why the JF-17s coming out look better constructed than your average Russian or Chinese aircraft.

Not sure about the learning from Saab systems, but once the jets were destroyed, Pakistan would have access to every hair of the aircraft both on the platform and the radar - which may have been protected and inaccessible before. You never know in which form and shape blessings reach you.

When PAF was repairing the SAAB 2000, they found that Saab used a different method of riveting / manufacturing that provided a superior finish. They were able to replicate this through some ingenious method. I'm simply wondering if those techniques managed to find their way to the JF-17s.

Interesting info in KE radar

From the comparison between the prototype and the radome, it can be inferred that the ZDK-03 radome has a diameter of 8.5 meters and a thickness of about 1.5 meters. These dimensions are smaller than the E-3A radome, and the latter is more than 9 radomes. The meter has a thickness of nearly 2 meters, so the antenna size of the ZDK-03 radar is smaller than APY-1. The radar uses the higher frequencies, so it short wavelength, an antenna relative size (ratio between the antenna and the actual size of the wavelength) on a large, while the gain of the antenna (antenna effective aperture ratio of the square of the wavelength) is also higher, It means that the radar has a large detection distance. Considering the problem of signal strength reduction in atmospheric transmission, the ZDK-03 radar should work in the S band . Although the remote performance of the S-band is smaller than the L-band, its accuracy is better. The main selection band of the detection and guidance radar.

The radar used by ZDK-03 is the second generation of airborne early warning radar developed by China in the 1980s. The radar mainly solves the shortcomings of the first generation of poor visibility, and adopts the pulse Doppler system.

This may not be entirely applicable today; the PAF has reportedly changed the KE's radar to a different AESA model (away from the ZDK03 PESA). @messiach CETC also has a ZDK06 AESA platform.

Are you suggesting the balance beam radar array fitted inside the rotodome? I am yet to see a single KE with a balance beam in Pakistan.

Not the balance beam system. Its a different system/part altogether and installed in a dual array scanning X degrees in the vertical but fixed in the horizontal- the dish rotation takes care of horizontal scanning.

So the mechanical disk rotation is still there. Similar arrangement was there in the first version too. Only the radar has changed?

Yes, the radar is the only thing changed. Most cost effective upgrade within budget.

Searching the zdk06 took me to this brochure.. from the info on it, seems like a decent upgrade.

The upgraded radar at a glance:

The ZDK-06 type early-warning aircraft exported by China adopts an active phased array radar antenna. The electronic scanning technology is faster, the radar beam has better directivity, and it has the ability to search the sea and the sea. At the same time, the S-band is used, which can have certain anti-stealth capabilities. The radar has a maximum detection range of 450 kilometers. The effective detection range for fighter-type targets (radar reflection area of 5 square meters, generally Su-27 or F-15) is 280 kilometers, for 1000-ton surface ships, the detection capacity can reach 300 kilometers. Such a radar, horizontally contrasted with the Swedish PS-890 "Ai Li eye" phased array radar, is in a leading position in overall performance.

The ZDK-06 early warning aircraft exported this time is the foreign trade type of Air Police-200. It adopts JY-06 active phased array radar and has the ability to monitor air and sea targets. Such flexible military and trade means will further enhance China's early warning aircraft radar technology.

Modified export version of the KJ-200 AESA balance beam radar.

Yes i am aware. This is a seperate program.

So, the PAF zdk-03 not upgraded with the JY-06 radar array?

What SIGINT aircraft does Pakistan have?
