abstractWe consider imaging strategies for synthetic aperture radar data collections that span a wide angular aperture. Most traditional radar imaging techniques are predicated on the assumption of isotropic point scattering mechanisms, which does not hold for wide apertures. We investigate point scattering center images for narrowband, wide angle data, and consider the effect of limited persistence on the resulting images. We investigate imaging strategies that apply to wide angle apertures. We show that coherent processing of the entire wide angle aperture may not be the best image formation strategy for objects of practical interest. Finally, we present initial results on resolution enhancement techniques for wide angle apertures.
