Multiview Three-Dimensional Interferometric Inverse Synthetic Aperture Radar [PDF]

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 ...

Fast Matrix Inversion and Determinant Computation for Polarimetric Synthetic Aperture Radar [PDF]

Computers and Geosciences, no. 119 (2018), pages 109-114, 2018
This paper introduces a fast algorithm for simultaneous inversion and determinant computation of small sized matrices in the context of fully Polarimetric Synthetic Aperture Radar (PolSAR) image processing and analysis. The proposed fast algorithm is based on the computation of the adjoint matrix and the symmetry of the input matrix.

Autofocus for inverse synthetic aperture radar (ISAR) imaging [PDF]

Signal Processing, 2001
Autofocus is a key step of inverse synthetic aperture radar (ISAR) imaging. In this paper four new approaches to autofocussing based on the application of beamforming and subspace concepts to ISAR imaging are developed. Their relations to maximum likelihood (ML) estimation are identified.
