SPY-6 even in 4.26 m/14 foot is very capable, the 20 foot/6.1 m variant initialy planned was better vs Ballistic missiles, SPY-1 A - D do 3.7 m/12 foot.
What is electical power of a AB ? and AEGIS like Chinese DDG 052C/052D also if it is possible.
052D Type 346A 4.3 x 4.3 meter/14 foot
055 have 346B ? a little more larger
And for 052C ?
The power generation capacity for a Flight IIA is 9MW, while for the Flight III it will be 12MW. I don't think we have any information on the power generation capacity for either the 052C or the 052D, though I would guess it would be slightly less than the Flight IIA, perhaps 6-8MW.

plus later I was guessing (but didn't post as LOL it was based on the height of individuals standing in the Type 055 bow in some picture) the side of the Chinese radar from the above post to be five meters, so the area would be about twenty square meters
It's possible that the panels are about 5m tall in actual length/width (vs slanted relative length/width due to perspective), though you have to remember that the actual radar itself is going to be a little smaller than the panel size, by an unknown amount, unless you can accurately measure the width of the panel cover "lip":
But even if you can get the lip measurements correctly, there is no reason to believe that the T/R modules will be arranged to completely fill up the surface area underneath the panel. Here is a 052C panel by way of an example:
In any case, going from the 052C to the 052D there is a definite increase in radar size:
You can see that the 052D's radar is wider, though not necessarily taller, compared to the 052C.
Going from the 052D to the 055, I don't think there is a physical size change, however:
As you can see, they are both just under two decks height, and if they are not the exact same size, then they are at least very nearly the exact same size. I have mentioned before that the 346A (which is what I'm calling the radar on the 052D), may be different from the radar on the 055 (346B?) in that the 055's main panel may be composed entirely of S-band T/R modules, whereas in the 346A (and the 346), the main panel consists of a mixture of S-band and C-band modules, which BTW is the answer to a long-unanswered mystery as to how the HHQ-9s were being terminally guided. The C-band modules were arranged into two 'bars' of modules above and below the S-band main section, and were responsible for providing terminal illumination for the HHQ-9s. Probably something like this:
Where the red bars are the C-band modules and the orange middle portion consists of the S-band modules. I think both the 052C and 052D's radars look like this, except that for the 052D there of course won't be any of the rectangular holes in the 4 corners for air ventilation (as it is liquid-cooled). If there is in fact an X-band radar on the main mast of the 055 (or it could actually be C-band also), then the C-band bars of the 052C/D will have become redundant and therefore removed from the main array, resulting in the entire main array being filled with S-band modules. So even if the size of the 052D and 055 main array panels are physically the same dimensions, it may be that the 055's main array is actually larger than the 052D's when measured in terms of the number of S-band modules present.
