  • An exact analytic solution for the 2-dimensional point target reference spectrum is difficult to find for bistatic SAR image formation due to a double hyperbola in the bistatic range migration equation. Four methods of the point target reference spectrum are analyzed, namely Loffelds Bistatic Formula (LBF), Method of Series Reversion (MSR), Geometry-based Bistatic Formula (GBF) and the Dip Move Out (DMO) approach. The link between GBF and DMO is given in detail in this paper, and also the link between MSR and LBF is validated by simulation results.
