OK, you're not talking about a radar, you're talking about an EMP

It's apparently both. Plus it seems to be able to blast all available
data to a satellite so headquarters has a full 3D view of the entire
theatre, everything all the planes and drones can see.

I find a combined radar/weapon in something the size of a fighter
a little hard to believe.

So google it and believe what you will.

Little problems like how do you store energy on the order of hundreds
of megawatts and how do you transfer it to the RF generators in
nanoseconds. Wires have inductance.

Each of the tiles apparently has local capacitive energy storage and a
a laser-triggered switch that dumps the cap energy into the antenna,
probably as a UWB ringing impulse. I've seen a blurred pic of the BAE
switch, and it looks like a small strip of amorphous material
(possibly doped diamond?) on a ceramic substrate. High peak power
laser-triggered semiconductor switches have been around for a decade
at least. 10KV x 10KA = 100 MW, not unreasonable if you've got G$ to
spend.

The capacitor HAS to be local to get around wire inductance.

OK, now you have some switched power, what generates the RF?

Where do you put the receive antenna(s) if this thing is also a
radar?

Matter of fact, where do you put any of this stuff? There isn't
that much forward looking surface on a fighter.

Cool stuff.

I'm not holding my breath.
