This letter introduces novel processing structures enabling the formation of 3-D inverse synthetic aperture radar (ISAR) images from phased arrays. Unlike previous approaches to 3-D ISAR imaging, this approach uses a spatio-sensor multilook processin

Conventional single-channel synthetic aperture radar (SAR) cannot directly measure or correct for smearing and distortions due to scene motion. Previous theoretical efforts have pointed out that this deficiency can be overcome using an along-track mu

The velocity synthetic aperture radar (VSAR) algorithm separates the radial velocity components present in a SAR image. These velocity images can be recombined to form an image with the corrected radial motion or further exploited for the purpose of
