Drone-based 3D interferometric ISAR Imaging

Three-dimensional (3D) radar imaging of non-cooperative targets has become very attractive as it significantly improves the more traditional two-dimensional radar imaging technology. Drone-based radar systems, on the other end, offer a very flexible, easily deployable and low-cost solution for airborne radar imaging applications. This paper introduces the concept of drone-based 3D radar imaging via an interferometric/ISAR imaging approach. The theoretical work presented in this paper sets the ground for this new technology and simulation results provide some example of the ability of this system to provide 3D radar images of surface moving targets when imaged by a set of drones.
