Study of Point Target Spectrum for Bistatic SAR Imaging
双基SAR成像的点目标解析频谱研究

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 Loffeld's 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 ...
