We ran some tests last year with the emitter built to spec. Looking at the output with a scope, you could see reflections from virtually everything on the field especially the player stations. You would think that reflections would be fairly well attenuated but they were not. Range finding on just signal level would be near impossible with the emitter assy from last year. I think that the only thing that would reliably give you data would be some type of time measurement. Since the emitters are not synchronized nor identical in output, the wave interference does not allow measurable data in that realm either. The distances are too short for any of our hardware to accurately make calculations based on time measurements even if the other problems were not present.
