N2 - The diving squinted SAR (Synthetic Aperture Radar, SAR) has the feature of non-uniform resolution in different direction. The resolution description is seriously restricted in the traditional SAR, which is not applied to the analysis of resolution in the diving squinted SAR. In order to illustrate a complete description of the resolution characteristics, a method of resolution analysis of squinted SAR based on distinguishable ellipse is presented. The expression of distinguishable ellipse on the slant and ground plane is derived respectively by GAF (Generalized Ambiguity Function, GAF). The simulation results show that this method is adaptive to the conditions of different geometry and system parameters, which can provide a theoretical basis for the design of system parameters and geometry configuration in squinted SAR.
