OK, you're not talking about a radar, you're talking about an EMP
weapon.
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.
The military reference says that they power and store the energy beam
equipment with resources that are used for VTOL hardware in other models.
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.
Wires have less inductance if they are really short.
No ****?
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?
Don't know
Where do you put the receive antenna(s) if this thing is also a
radar?
Pulse radars use the same antenna to send and receive.
Yeah, but the implication was the little 4 inch dodad was a megawatt
source. Now it's a receiver front end too?
Matter of fact, where do you put any of this stuff? There isn't
that much forward looking surface on a fighter.
Put it under a streamlined radome.
Not a lot of area there for gigawatts.
