This could be the third one, the second one should be further left from this one in the red circle.
Also the second one should be in a more advance stage of assembling with the island on it.


From the latest info I have, there is no third one, since the way it is assembled is different to the first two ones.

Do we know anything about this radar? The first two images show the PLAN's integration/test ship. The radar appears visually similar to the one installed on the 075. Could be from the same family.

Both radars appear related. The one on the Type 075 is a dual band that it is presumably an S-band in one side, which is the bigger side, and the X-band on the other side, which is the smaller side. The S-band is angled a bit more to the sky to facilitate aerial search, while the X-band is towards the horizon and the surface, which makes it intended to search for sea skimmers that can pop over the radar horizon.

On the new radar, it seems to me the panel is like the first radar's S-band panel but turned around 90 degrees, so it is taller than it is wider. This improves the ability for the radar to do elevation scans at the expense of horizontal scans. The new one is both S-band on each side, no dual band here. Given the angle of the face, its optimized for aerial volume search. I am not sure of the dimensions but it appears to be around that of the Type 382 Top Plate.

The final model for the new radar is not likely what you will see here. Just like the Type 075's new radar, they may add things on the side and on the top, for the purpose of reducing the radar's own radar reflection against enemy radars.

There might be a possibility that the next Type 075 might switch to this, and if not, the next ship after. A possibility this may be used instead of future destroyer upgrade programs, and maybe even on the Type 054A upgrade later.

The new solid state radar on 075's aft mast superficially resembles the new twin sided radar on the test ship, but I don't think we have a reason to think they are necessarily "related".
There are only so many ways to design a modern, rotating AESA for a naval ship, after all, and all forms of grey slabs or rectangles on a rotating mount will begin to resemble one another eventually.
E.g.: the external similarity between Smart S, Artisan, and SR2410C, for one, or SAMPSON and EMPAR

There is also a significant size difference between the Sea Eagle radar on 075 (which we've demonstrated that the new radar being tested on 892 is similar in size to) and the much smaller new aft radar on 075.

However I do agree that the new radar on the test ship 892 seems like a good candidate for replacing ships currently serving with Sea Eagle radars, if structural modifications and power/cooling/volume allows for it.

That looks bigger indeed. Despite its size, one of the mentions and rumors of the alleged "Type 383" is that the S-band size has a range of 350km and the X-band side is over 100km. The shorter range of the X-band is understandable, but if 350km is true, that exceeds the Type 382's range of 300km, despite having a much smaller face. Then how much more powerful the new radar then if the faces are the same size as the Type 382.
