Yup. This is exactly like encouraging UFO reports that were actually the U2 spy planes.
Great cover story, and adds mystique about the US Military/Industrial complex's abilities to boot. "Oh, those signals you're picking up that we are leaking accidentally? Sure, that's aliens, keep listening to 'em." That way they get to understand what kind of crap INFOSEC they are dealing with on the base, what can be leaked, and if anybody else picks them up... well, it's aliens.
Even if somebody figures out it's coming from the base, well, the US is talking to aliens because our military knows everything and is all-powerful.
You turn a giant cluster-F into your own internal security mechanism for free, and give the illusion of competence.
