Seismic radar using time reversal mirrors

Abstract

A new application of Time Reversal Mirrors (TRM) is introduced in this work. It is similar to radar surveillance, detecting and tracking moving object(s) in a remote area using seismic waves; this includes the exact location of the moving object and its speed. Recordings of high signal-to-noise ratio reference Green's functions are required, where they are used as calibration records or moving sensors. The proposed method is tested with a field experiment.
