A colleague recommended putting a frequency emmiting device inside/on top of/attached to the aarow and then using a frequency sensor behind the target?
A 'frequency emitting device' is so vague as to be meaningless, was the suggestion to emit a frequency of sound, light, radio or some other emission with a frequency ?
What would be the best sensor or series of sensors to detect if an object is present in a large field? Specifically, shooting an arrow (5mm diameter) into a large (10ftx10ft) target. I don't need to know the location of the aarow, just yes or no if it is anywhere on the face.
