Going a bit OT...
I suspect any advantage they have over SPY-1 is the same as indicated in the paper - mostly ship-impact issues such as weight and power loss.
Regarding the system installed on the 052C of the PLAN, please bear in mind that the nature of the radar is my speculation based on the presence of what appears to be separate external Tx. horns, and the fact that the associated SAM seems to be related to the SA-N-6, but with some interesting changes to the launch concept (non-rotating angled launchers, as opposed to rotating vertical ones). All manner of speculation and flat out disinformation abounds regarding advanced Chinese equipment (1980's Cold War, anyone?) including claims that the radars are "Active arrays" (Which only the UK, Japan, Germany (et al) and Austrailia (And US?) are close to fielding on ships) or that the arms are "Test equipment" (Bit of a funny place to put it).
The interesting thing is that 052C has the Yagi-type item aft, which is either a low-frequency surveillance radar (Rendering most RCS-reduction ineffective?) or some sort of ECM. There are several small items of equipment on either side of the mast, and my moneys on those being the ECM / ESM systems, with the larger apparatus being a radar. In addition to this, they carry the phased array radar, but no separate fire control radars (apart from the usual radar GFCS over the bridge). This would imply that either the phased array has some multi-function capability (which would make it somewhat different to any Russian forebears) or that the terminal homing is done via the missiles, either Active Radar Homing or Track-via-Missile, as in PATRIOT. Given the various claims of PATRIOT details being passed / leaked to China, it may well be the latter. Now I'm curious as to whether this was intended as a way of getting a radar transmitter (in the missile) close to a suspected stealth aircraft (cued from the Yagi-set) thus increasing the effectiveness vice a system that relies on the ship-mounted radar to aquire the target.
As always when one plays at being a CIA analyst, it can be best to simply "say what you see" rather than what you hear...
