Abstract:
This paper describes a communication system in which sending and receiving terminals automatically generate beams focused upon each other, which arise solely from ambient noise. The terminals are amplifying retrodirective arrays of antenna elements. Analysis and experiment are used to prove and verify the system concept. Some engineering considerations pertinent to system operation under various conditions are also analyzed and discussed.
