Multiview Three-Dimensional Interferometric Inverse Synthetic Aperture Radar

IEEE Transactions on Aerospace and Electronic Systems, 2019
Three-dimensional (3D) inverse synthetic aperture radar (ISAR) imaging has been proven feasible by combining traditional ISAR imaging and interferometry. Such technique, namely Inteferometric ISAR (InISAR), allows for the main target scattering centers to be mapped into a 3-D spatial domain, therefore forming 3-D images under the form of 3-D point ...
