Abstract
The focusing resolution effects of time reversal mirror (TRM) are studied based on time-reversal focusing theory. Using the coherence of multi-path the effective aperture of TRM is enlarged and focusing gain can be obtained more than 10dB. Focusing resolution with a TRM through random medium is much better than that obtained in homogeneous medium.
