THE CHIRP SCALING ALGORITHM OF ARBITRARY FORMATION BISTATIC SAR IMAGING
The paper derives a chirp scaling(CS) algorithm for arbitrary transmitter and receiver motion (nonparallel tracks,unequal velocities and antenna squint) in a bistatic synthetic aperture radar(BiSAR) constellation.Based on the bistatic geometry and Taylor series,two halves of monostatic phase histories are expanded in two Taylor series around the individual points of stationary phase to derive the point target spectrum. A novel range scaling formulation is proposed based on the spectrum.Finally,the proposed approach is verified with a point target simulation.
