Theoretical analysis and validated experiments of the localization by superposing beats

Many everyday life activities require precise localization information. Navigation by means of the global positioning system (GPS) is a well-known example. Despite its broad usage, this localization method cannot be utilized in all application areas. Logistics, factory and laboratory automation, as well as warehouse management, for example, require the low-cost localization of various objects with a precision of a few centimeters, particularly in indoor environments. For this application domain, this paper proposes a new procedure to measures the relatively distance difference between two points (e.g., transmitter) to a third point (e.g., receiver) with a low resource complexity. The procedure based on the superposition of particularly parametrized beats. In addition, this paper also presents a preliminary theoretical analysis as well as some laboratory experiments.
