PLA AEW&C, SIGINT, EW and MPA thread

For a 12 hour flight mission, I think 3 crews would be preferred, with each crew work for a four hour shift. 2 crews are also possible but they will have heavier workload and may get fatigue and risk making errors.

If one crew consist of 12 members, that would be 36 persons (3 crew) on the flight.

It can give a far superior ultra long range positive target ID, including on ground targets.
Also, very long range detection and tracking of small objects (missiles).

On this topic, it could also possibly augment radars designed to guide counter-battery fire.

One AI application I haven’t heard people talking about is reducing crew working load through application of AI based data analysis. Wonder if that will be incorporated into KJ-3000.

It's probably not worth talking about because some extent of AI based data analysis is going to be utilized in every aspect of computing/data management/analysis.

These days, saying something is "AI based" is like saying our computers are "electricity based".

I really hate that marketing. As it's very loose in definition and often followed with "this can allow firing missiles etc"

If one stick to say, K.Barton's "Radar System Analysis and Modeling". Page 449 have this :

NO AEW radar will meet this criteria for missile or gunfire control. APY-9 may still have mainlobe width of some 7 Degrees which, well not a "fire control grade" as per K.Barton's book above. Even fighter jets, typical fighter radars have mainlobe of about 3-4 degrees. Very rarely 1 Degrees and that is usually for ground attack as narrow beamwidth helps in getting clutter away and to get better resolution in real-beam mapping.

The better approach is perhaps should be SNR as probability of detection and tracking relies on SNR. Radar "lock-on" or Tracking is typically initiated at very high SNR condition e.g 24 dB. Which correspond to 90% PD for Swerling-1 Target. Also the angular accuracy can be calculated more definitively. This approach is more "frequency agnostic" as you can do this in any frequency.

I'm not sure why you would need that much accuracy for missile fire control as for gun fire control since we are invariably going to be talking about ARH AAMs these days. Perhaps what Lockmart refers to is the ability to guide an AMRAAM or SM-6 to the appropriate homing basket for its own radar seeker to acquire the target.

Anyone have numbers on roughly how many Y-8Q MPAs in service by now? This year's IISS says 25+ but that seems low.

Any Y-9Qs spotted in service since that one image on page 287?

New ASW aircraft in serial production, likely to be Y-9FQ/GX-15.

 

[asif iqbal]

The Y-9 platform has been a really good platform for these special mission aircraft

 

[Deino]

Could this be another KJ-3000 with the radome not yet installed? ... and (via Foolsball) "This photo might be more interesting, a KJ-600 shipborne AWE still only in green primer. Could mean a new batch of KJ-600?"

Cross-posting from the Transport thread, as this is of relevance here.

A paper on numerical simulation of the aerodynamics of a large strategic transport. Filing it here for record keeping, since there have been signs of China working on a large transport in the same class as C-5 and AN-124. Of particular interest is that the paper examined the aerodynamics of an early warning variant mounting an impressively large radome.

EDIT: I want to emphasize that the dimensions and specs of the models in this paper are not to be taken literally, as the paper mainly has to do with validating the usefulness of the numerical models in designing large transports and early warning variants based on them.
