Abstract: We consider the problem of wide-angle synthetic aperture
radar (SAR) imaging from data with arbitrary
frequency-band omissions. We propose an approach that
involves composite image formation through combination
of subaperture images, as well as point-enhanced, superresolution image reconstruction. This framework provides
a number of desirable features including preservation of
anisotropic scatterers that do not persist over the full wideangle
aperture; robustness to bandwidth limitations and
frequency-band omissions; as well as a characterization
of the aspect dependence of scatterers. We demonstrate
the effectiveness of the proposed approach through experiments
based on electromagnetically simulated realistic
data.
