A new and practical formulation of bistatic Inverse Synthetic Aperture Radar imaging and verification of the formulation using numerical examples

A compact formulation of bistatic inverse synthetic aperture radar (ISAR) imaging is provided and presented thru numerical simulation of various perfect scatterers. The imaging formulation is derived for small-angle and small-bandwidth conventions. After completing the formulation, its relationship to monostatic set-up is examined and discussed. To validate the algorithm, the images of point target models are then simulated and presented for different bistatic geometries. It is shown that for a range of bistatic angle, the imaging algorithm successfully works and has the advantage of reduced bandwidth over the monostatic case at the cost of worse resolution.
