Time-reversal (TR) has the advantages of space-time focusing and super resolution. In this work, the effects of random media on TR focusing and imaging are analyzed. The simulation experiments are carried out to investigate the performance of TR focusing and imaging, in cases of different array sparsities, varying optical depths, different locations, and different albedos of the random medium. Results indicate that the multipath scattering within the random media enhances the super resolution capability of TR imaging. Also, the imaging performance of TR focusing shows considerable adaptability to various random media parameters and array sparsities.
