Three Dimensional ISAR Autofocus based on Sparsity Driven Motion Estimation
, 2022 S.51-56Inverse Synthetic Aperture Radar (ISAR) exploits the motion of the target to achieve cross range imaging, as opposed to its range resolving capability (along line of sight) which relies on the bandwidth of the signal.

Application of optimal sensor positioning to bistatic ISAR
, 2012 Bistatic ISAR (B-ISAR) imaging has recently been considered to overcome some limitations of monostatic ISAR systems. The target projection on the ISAR image plane depends on the target's own motions and on the relative position of target transmitter and ...
