Nonstandard image formation methods can enable fully threedimensional 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,...
We develop a feature-based shape- and motion-estimation scheme for moving radar targets based on the solution of object-image relations (OIRs) for incomplete and noisy data. Unlike previous OIR-based techniques for the radar moving-target-imaging problem, our approach is robust to 1) missing data, 2) so-called “slippery scatterers” whose location moves with respect to the radar viewing aspect, and...
