The military applications are obvious, I assume. "Qanat" might even be a code word for terrorist hideout and underground infrastructure.

This is just racism.

GP might have meant that the researchers are veiling their actual goal, in the vein of "detecting humans in drone feeds and autonomously dropping bandages on them for search and rescue"

This is how I interpreted the comment.

Spy satellites surveying Iran in order to detect underground water infrastructure seems like, to me, the ulterior motive is to identify infrastructure so that it can be compromised in some way, likely with drones and bombs.

For some reason, the article is inaccessible at the time of writing, but it seems to be using a military satellite to map ancient (and presumably shallow) underground water canals for archeological purposes.
