Do you know the improvements over the "old" one?
CV-18 Fujian is the first one.
So, beyond the brochure. Is there any deeper information about the export "Type-052DE" ?
Things like how much it would differ from one used by the Chinese navy ? I'm particularly interested with the export version of the Type-346A for the DE. This one is literally the biggest other than US SPY-1, naval air surveillance radar in export market.
European offers includes Seafire, Kronos, Hensoldt are all sub-4 m diameter/width aperture. Which limit their power aperture product against possible future threats like hypersonics or low observable threat. The biggest would be the SMART-L/S-1850 family but no one outside Europe are getting that as far as i see.
The other thing is of course cooling and power generation thingy. For example our Arrowhead variant will have 4x 1.3 MW generator (total capacity 5440 KW) and expected at least from the number of crews a hotel load of some 500-600 KW. Thus 4.8 MW for other thing. The radar might take some 40% of that or perhaps less.
From there, one can then try to relate the tracking capacity of the radar with the available prime power. The more power the more targets it can track, more power also help with tracking accuracy especially against low RCS target.

Nice, thanks for posting. This part is especially interest me :
So type 346 was 4678, 346A is 5700. 346B Which claimed to be 40% larger might have some 20 sqm antenna and thus assuming same Frequency (2.94 GHz and element area of 0.00258 sqm) It will have 7980 TRM.
346A/B are the same size and both are 40% larger than the 346. Remember, the difference in beam is only 2m between 052D and 055. The 346B is a tight fit on the 055. The 346A is a really tight fit on the 052D.
Mk1 eyeball tells me so.
I really don't see the 346B being 40% larger than the 346A. 40% larger than the 346? Sure.
Compare pics between 052D and 055 and bear in mind the difference in beam is just 2 meters. They come out the same size.
I believe the major difference between the 3 variants are the following:
346: Early gen AESA
346A: Larger array 5x5m, better modules (still) GaAs
346B: Same size but newer and more powerful modules based on GaN
The Turks have the same approach to the Cenk600-N on the TF-2000 and their aircraft carrier. Estimates are also 5x5m aperture and ~750km range.
Surely there have been precise measurements of the dimensions of 346, A & B after all these years. Anyone have an image?
