Synthetic Aperture Imaging of Direction- and Frequency-Dependent Reflectivities
Synthetic Aperture Imaging of Direction- and Frequency-Dependent Reflectivities
We introduce a synthetic aperture imaging framework that takes into consideration directional dependence of the reflectivity that is to be imaged, as well as its frequency dependence. We use an $\ell_1$ minimization approach that is coordinated with data segmentation so as to fuse information from multiple subapertures and frequency subbands. …
