I know just thought it's weird to put them slap bang in the middle of a radar array. PeeD did say one possibility was that these 'sub-arrays' are just maintenance hatches... looks unlikely to me, but it's a possibility.
@AmirPatriot, the F-22 achieves a 0.0001M^2 RCS at only certain angles, most likely at the front. I don't think it can achieve that level of RCS against SAMs. @PeeD's calculations were likely base on different RCS values.
Also please beware that once you have AESA, you can do some signal processing and filtering to identify signal anomalies for each TRM. Remember, you have so much control over each TRM, that you you will know the time of flight for each signal initiation as well as the wave form.
Combining this with Bistatic nature of this system as well as presence of powerful OTH and VHF radars as part of an integrated air defence, we have a robust anti stealth system.
