The study of focusing resolution with time reversal mirror in underwater acoustics

摘要：

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