i think there's a chance we won't be seeing the actual radars installed on the starboard side of the ship, which would be a bit sad. that goes for both S band arrays on that side. Since two sides of the ship are the same, there's no reason to test all of them. And the port side of the mock up, facing the large lake, seems more useful to test equipment. Sadly, it's also the side we might have harder time getting images from. Unless someone gets a boat and uses a very long lens.
I would expect, however, the x band array on the back. Though that too might be hard to photograph. Most interesting thing to follow will surely be the rear radar.
If all of the missiles on 055 use self guidance for terminal phase, relatively lower front arrays won't really matter. I would expect to see the same arrays as on 052d, meaning they'd be used for midcourse guidance as well. Which means x band is free to be used for early warning only. If so, i'm actually surprised to see the largest opening on the mast to be where it is, height wise. On such a large ship one could easely afford to put the radar very high up. And the large holes seem to be around 25-27 meters. Certainly high, but not as high as sampson on type 45.
Though if the real x band warning radar will actually go on top of the mast structure, (but what are the holes for then?) then we might be talking about a 30-32 meter high array.
Is it possible we might see two sets of x band arrays? One high up for early warning and then more arrays where the holes are for... missile communication? I guess that'd free the large S band arrays to be used for volume search and tracking only, possibly increasing the overall number of fire channels.
We do know that hq9, as opposed to hhq9, uses higher frequency dataink for missile communication. Maybe the future naval hq9b is also going to go that route. But that'd also suggest there are going to be at least some differences between the S band array on 052d and ones on 055.
