I want to know so so badly what radar & em systems look like for top of that line military gear. Obviously they're not gonna tell us, but I really hope it's astoundingly gargantuan throughputs, massively crazy FPGA and DSP processing. Perhaps very near to the antenna arrays?

We can look at systems diagrams for stuff like the modular AN/SPY-6 the Navy uses, which is already a decade old design, and it's a racks and racks of power supplies, array control, and processing. What must be in there! What absurd interconnects must stitch it all together! https://en.wikipedia.org/wiki/AN/SPY-6

I can only hope there's much more advanced equipment already deep into development, being readied for aircraft! (Then again, the crucial E7-A wedgetail aew&c basically gave up on trying to find a modern sensor solution for now, maybe might get an update later, if any get built at all).

This was a fun article to go through though.
