“…In efforts to solve this problem, this study presents a novel method which allows the collection of radar data of a target with a theoretical motion of up to 6 Degrees-of-Freedom (DoF) during a multistatic SAR collection, without requiring the target to actually move. The practicality of this method is demonstrated using ground-based synthetic aperture radar (GBSAR), which is highly regarded for its accurate repeatability and flexibility in testing many SAR configurations [4][5] [6]. Section 2 expands upon the method by introducing the multistatic radar system and scene used to obtain simulated and experimental results in this study and the hybrid SAR/ISAR conceptualisation behind this method.…”

There is great interest in multistatic synthetic aperture radar (SAR) systems as they are capable of providing high resolution images. These systems could prove promising candidates for provision of surveillance for both military and civilian interest. Both multistatic SAR and its counterpart, multistatic inverse synthetic aperture radar (ISAR), are limited by their assumptions of observing a stationary target from a moving platform and vice-versa. Hence, without adequate target motion compensation, their resultant radar images appear defocused. Arranging experiments capable of providing repeatable multistatic hybrid SAR/ISAR data of real moving targets can be difficult and costly. One viable approach is the novel method presented in this study, whereby multistatic hybrid SAR/ISAR data can be collected of a target moving with a theoretical motion, without the requirement of an actual moving targetthe theoretical motion is brought about through the appropriate motion of antennas. The study demonstrates, both through simulation and experimentation, how radar trajectories of a given SAR system can be altered to arrive at the equivalent setup of observing a moving target. Results from simulation and from an experiment conducted at the Cranfield University Ground-Based SAR (GBSAR) laboratory are presented, showing the utility of this approach.
