Abstract :
Synthetic Aperture Radar (SAR) has been applied in civilian and military fields widely. In this paper, an Omega-k imaging algorithm for ST-BFSAR is proposed. Different with monostatic case and translational invariant bistatic SAR, ST-BFSAR is 2D variant along azimuth and range directions. To deal with this special phenomenon, the algorithm performs a 2D interpolation operation. This method can also be used in the focusing of general bistatic SAR with one stationary station.
