There was a talk by Steve Blank where he was explaining US investment into radio astronomy(arecibo for example) by military projects aiming to establish the signatures and order of battle of soviet radars. They would measure the reflection of radar signals from the moon.

Can you share a link, if possible? The only one I found was an hour long talk hosted on youtube [1].

Thank you!

0:51 in that talk. Though it doesnt mention arecibo specifically(i might have mis-remebered it) its still a fun thought.
