Compressive sensing and 3-D radar imaging

Nonstandard image formation methods can enable fully three-dimensional fine resolution radar images of some objects of interest to be constructed from certain types of sparsely sampled three-dimensional apertures, which contain too little collected data to support traditional imaging methods. Such three-dimensional image products provide more target information than traditional SAR and ISAR imagery, and eliminate most of the difficulties associated with interpretation, mensuration, and recognition that result from overlay effects, self shadowing, scaling and viewing angle uncertainties.
