So, it has subarays, and most likely the phase shifters controlled digitally not SDR Tx/Rx modules.Do you seriously think that LM would disclose proprietary information on the F-35?
The following is the technical reference that configuration exist at the sub array level with the F-35.
At least there is evidence to sufficiently debunked your view that it cannot possibly happen at the sub array level.
What would you expect to see then on the backside? This video is closest yet I've seen of the RMA and TRM assembly and its interfacing:The subdivision of MRAs or subarrays in the SPY-6 suggest to me that digital beamforming is in the subarray level.
Question is how they define the "fully digital " ?What would you expect to see then on the backside? This video is closest yet I've seen of the RMA and TRM assembly and its interfacing:
The presenter claims the radar is fully digital.
This 2nd WW radar has a few interesting features.
Good question.Question is how they define the "fully digital " ?
Doesn't matter how you do that there have to be a synchronise signal across all module, and that needs same coaxial , D-sub won't be enough.
I think the synchronous connector is on the backplane of the radar.I did spot one coaxial port (J4) on the lower left of the RMA. More interesting, there are fiber optic cables, one per TRM, going into the RMA both left and right (24 in total). That could be used for synchronization. Take a look at this:
Why are they showing this much detail to the public?
