I don't suppose there is any way that you could detect a gamma ray or neutron source or the increase in temperature caused by the structure of the ship absorbing some of this vast amount of radiation that is pouring through it?
If it's radiating neutrons you have a big problem with neutron activation of the drone--it's going to come home radioactive. Thus it pretty much must be gamma radiation.
However, current gamma ray detection has major problems with focusing--the gamma ray telescopes have very, very low pixel counts. Even a substantial gamma source isn't going to be able to be pinpointed even if you can tell it's out there somewhere.
