摘要: 该文建立了斜视SAR的运动误差模型，分析了不同斜视角度和波束宽度情况下运动误差造成的影响，提出了小斜视和大斜视情况下各自的运动补偿方法，分析表明该方法较常规运动补偿方法适用范围更广。仿真和实测数据的处理结果表明了该方法的有效性。Abstract: Based on the proposed motion error model and detailed influence analysis, with respect to different squint angle and beam width, novel motion compensation methods are presented in this paper for slightly squinted-looking SAR and highly squinted-looking SAR, respectively. It is shown that the application scope of the proposed methods is wider than the existing ones. Lastly, both simulation and results of real data are provided to demonstrate the effectiveness of the proposed methods.
