My guess is the same, a radar this size would be pretty weak, and I wasn't talking about the thrust of the engine, I was asking about the electrical power generation. I suspect it would be insufficient for a functional radar too.
There has to be an IR camera somewhere but we don't see it
Is it flying according to the ground radars? Is it seeing through the missile's IIR seeker? that has to be a pretty pathetic resolution.
It is not disclosed.
Maybe IR sensor.
We might also be dealing with arrays of drones and ground based radars.
Phased array radar elements can be separated into multiple drones.
