Abstract :
Bistatic spotlight synthetic aperture radar (SAR) which uses a separated transmitter and receiver has been studied intensively due to its flexibility. The paper introduces omega-k algorithm for bistatic spotlight SAR imaging in the parallel track configuration. Using the principle of stationary phase (POSP) and the point scattering response (PSR) of bistatic spotlight SAR, an omega-k algorithm is derived, which is based on the geometry of bistatic spotlight SAR. Lastly, the algorithm is validated through point target simulations.
