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.
