High Resolution Microwave Imaging for Point Targets in Continuous Random Media Using TRMUSIC

Time reversal with multiple signal classification(TR-MUSIC) is a super-resolution imaging method for locatingand detecting hidden objects in complex environments,inhomogeneous, and cluttered media. In this study, the imagingof point scatterers in continuous inhomogeneous random mediais investigated. Furthermore the effect of random mediumstatistics on the TR operator eigenvalues and eigenvectors fortwo close targets is inspected. Because assuming a well-resolvedpoint like scatterer, the performance of the method for twoclosely separated targets is unknown. The novelty in this work isthe performance evaluation of the proposed method andevaluating the quality of the resultant images in random media.
