Even if you are looking at the turbines "edge-on," there's probably going to be a noticeable Doppler return as well.
Plastic drones with plastic propellers are still visible on radar because the tiny propellers spin super fast, so they light up like a Christmas tree on Doppler radar because the approaching vs receding velocities of the blades are so different.
Any chance you can explain to this idiot (me) the flaw in my thinking? https://news.ycombinator.com/item?id=39903084
Seems like another user with way more experience than me did an excellent job explaining the situation -- I enjoyed reading their answer!
