    Abstract
  • To compensate motion errors of images from the parallel-track bistatic synthetic aperture radar (BiSAR), an improved chirp scaling algorithm (CSA) is proposed. Since velocity vector of the moving aircrafts in the parallel-track BiSAR system can not remain invariant in an aperture, an actual aperture is divided into subapertures so that it is reasonable to assume that the aircrafts move with constant acceleration vector in a subaperture. Based on this model, an improved CSA is derived. The new phase factors incorporate three-dimensional acceleration and velocity. The motion compensation procedure is integrated into the CSA without additional operation required. The simulation results show that the presented algorithm can efficiently resolve motion compensation for parallel-track BiSAR.
