Three of the four radomes on top are SATCOMs or datalinks. The one in the middle between the IFF strip of the two Type 346A is a Type 364 surface search radar, and there is another Type 364 on the other side of the island.
002 has three ledges on each side of the island for Type 726 series ESM. But on the Liaoning there are four ledges instead of three, so one of the ledges does not have an ESM unit but something else. The ECM on both ships, and like on the 075, is set on the side of the hull.
Notice the tall pyramid extending from where the SATCOMs are, and on top of which is the Type 382 search radar and a TACAN? Note the pyramid has a square panel on it, and there is one panel on each of the four sides. It looks like a small phase array radar. Its a phase array but its not a radar. Its likely to be a high speed data communication unit, possibly for CEC or cooperative engagement. Its matched to similar panel set on the Type 055's pyramid integrated mast, just right above the four set of X-band radars.
