The Wuhan mockup still isnt fitted with any radar, and possibly wont be (as it would be kinda bad due to it near a population center and merely having a lake as test-range).
What we see here, is possibly the real radar-testing mockup for the 055, while the Wuhan one is, like the Liaoning carrier mockup, merely one for testing the crew handling.
I have one or two counterpoints: first, the Liaoning mockup was definitely fitted with radar, for a time -- in fact it had both the representative sea eagle and a few 346 arrays on it as well. We also never had any evidence to suggest the Liaoning mock up was used for testing crew handling. For one, we never saw more than one or two plane mock ups on the "flight deck itself," let alone deck crew. So I think the 055 mock up at Wuhan may yet have radars installed.
Still, it is possible that for some reason they've decided to not conduct extensive EM testing of 055's sensors at Wuhan for whatever reason. I'd be interested in waiting for more recent pictures to see if they've finally fitted anything on.
The more pressing question, is if the seaside 055 sensor test platform is meant to be representative of the real thing, then why did they equip a 346 rather than a 346A?
346A is obviously in mass production and operating well see as it is aboard all 052Ds without any issues that we know of, and the 346 is an older generation of radar. Not to mention all the rumours we've had over the last few years is suggestive that 346A will be on 055, and even the mockup's radar openings are square like 346A rather than rectangular like 346.
The most sensible reason I can come up with, given the above prerequisites, is that for whatever component of the EM test they are conducting at the seaside site, using a 346 instead of a 346A is considered acceptable. Why use a 346 instead of a 346A? Possibly because there are quite a few existing land based 346 arrays that can be taken either from original 052C test rigs or the Liaoning mockup, and producing a new 346A may be needlessly expensive and not an optimal use of production space when 346As are needed for use on real 052Ds being produced.
Still, I suppose we don't know enough to make a firm call either way -- we will probably know when we see 055 launched. If it has 346A style flat and square covers over its radar openings, or 346 style and round/rectangular covers, will be as good as confirmation of the kind of radar it will have.
