摘　　要：针对反射面天线体制星载合成孔径雷达(spaceborne SAR)的多角度成像姿态控制问题,文章提出了成像弧段划分规则、首景成像姿态策略、成像角度机动切换策略、第二景成像姿态的计算方法,并基于实测的场景图像仿真数据进行了姿态策略验证,结果表明:提出的姿态控制策略可以实现不同方位角的SAR成像。In response to the problem of multi-aspect imaging attitude control for spaceborne synthetic aperture radar(SAR)with reflector antenna system,the imaging arc division rule,first scene attitude control strategy,imaging angle maneuvering switching strategy and calculation method for the second-scene imaging attitude are proposed.The attitude control strategy has been verified based on actual scene imaging data,and the results show that the proposed attitude control strategy can achieve SAR imaging at different azimuth angle.
