Abstract
In this paper, we present an analysis and comparis on of several imaging methods of point targets in random scattering media. We derive the multi-static matrix and time-reversal matrix based on the mutual coherence function [1]. This i ncludes the interactions of the random scattering media with the targets of interest, which captures the effect of random media to the imaging of the targets. Several imaging modalities including time -reversal (TR) [2], time-reversal Multiple Signal Classification (TR-MUSIC) [3], Synthetic Aperture Radar (SAR), minimum variance beam forming (or Capon’s method), and modified beam forming (related to coherent tomographic array imaging) are applied to produce images and their performance s are compared. We also investigate the effects of the random media characteristics on the images.
