Heads up mods: this post is based on something Trump said in France today at the G7 conference talking about the Iran deal and other stuff before leaving. I do not have a linked article nor video clip of it.
Let me preface all of this by saying that as a polymath, I have several areas of interest including electronics, optics, music and religion to name a few. I've spent quite a number of years studying optics and image processing science. That said:
Trump today was going on about the Fordrow nuclear site and the buried uranium there. He was commenting that it will be hard to dig it out but ITMT, while we get around to it, that our Space Force (which Trump created) will be watching from orbit.
This is where Trump may have made a faux pas in inadvertently exposing a national secret:
In optics, there are relationships between aperture and resolution. There is both linear and angular resolution. General, the more resolution you want, the more aperture you need. But there are also modern computerized image processing techniques to artificially enhance resolution. For instance, we commonly deploy radio telescopes on opposite sides of the Earth both looking at the same object, then we synthesize an artificial aperture where the synthetic aperture is equal to their distance in separation effectively making a radio telescope with a synthetic aperture as big as the Earth.
While talking to the press, Trump let it slip that if anyone goes in there from Iran fooling around trying to dig out that uranium themselves, that we will see it. More than that, Trump went on to explain HOW WELL we can see them. He probably should not be talking about that. A very tightly regarded secret is HOW SMALL of a detail we can resolve on the ground from orbit. 10-15 years ago, I was certain that we could probably resolve a pack of cigarettes and identify individuals.
You see, the technology is out there now perhaps using some variant of enhanced adaptive speckling interferometry to resolve much smaller. Trump basically said that if we want to, we could read the name tags on their uniforms. Dear Donald: I don't know if you were just speaking off the cuff figuratively, or literally, but best not give our enemies any idea of our true capability, even in jest.
If we can indeed resolve that fine a detail from orbit (I have been able to identify a brand of cigarettes from a mile away and see detail in the scabs of rust on the head of a bolt on a street sign from a mile away (where the air is most turbulent from heat, etc.) with my own gear, and my father did aerial reconnaissance from aircraft during WWII, if you just gave away a tightly guarded secret, I can just imagine the people back in Washington pulling their hair out.
