Abstract
An RF beam is used to probe the presence or absence of a rotating blade in a known field of view. Timing of appearance or disappearance or 'zero-crossing' of a reflected signal is correlated with timing of the blade movement. Blades which are leading or lagging versus other blades will produce different timing signatures representative of alignment of the blades.
