Imaging of objects in the presence of rough surfaces using Time-Reversal and array processing

Imaging and detection of objects in the presence of rough surfaces and random media are important current problems with applications in object detection near rough ocean surfaces and terrain, and remote sensing in geophysical and biological media. It has also been important to incorporate signal processing techniques to space-time imaging. This paper presents applications of several signal processing techniques to imaging in complex environments, including Time-Reversal MUSIC imaging in random media. Also discussed are the effects of multiple scattering on several other imaging techniques including Time-Reversal, Modified Beamformer, and SAR. In particular, we discuss the imaging of objects located near rough surfaces.
