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 receiver. Although the target’s own motion cannot be controlled by the radar, the relative tx-target-rx positions can be somehow controlled or predicted in some cases. In this paper, the theoretical aspects of optimal sensor positioning for obtaining desired B-ISAR image projections are detailed. Results are then applied to B-ISAR in a maritime surveillance scenario.
