Yes I am sure about that. I have worked on back scatter applications for a long time. You are talking about long distance and getting a distinguishable signal in return. Noise is the killer. Yes it has been done for a long time. But they are trying for a remote unit that is not laboratory sized. It is NOT about computing power... it is the fundamentals
As yoi have expertise in back scatter apps, is it possible you can guide us to a face slapping app for use on our elected officials?
Anything that will enhance the effect of slapping them down in an election booth would be greatly appreciated.
