Distributed Time Reversal Mirror Array

Abstract

An array of independent, separate, distributed time-reversal mirrors (TRMs) that can function as a large array in a coherent (collective and co-operative) manner is described. Due to the unique feature of time-reversal to compensate for the propagation delay after round-trip, the DTRMA can perform coherent integration of signals across the array through distorting media without the need for complicated array calibration and precise geo-location procedures, even after the location of a TRM has been changed. Several proof-of-concept experimental results to show both temporal and spatial focusing properties of the DTRMA are demonstrated using commercially available off-the-shelf components and instruments.
