| 摘 要： | 姿态指向稳定度是合成孔径雷达卫星平台设计的重要参数。文中在卫星姿态指向抖动数学模型的基础上，利用成对回波理论推导了姿态指向抖动对聚束SAR点目标冲激响应函数的影响，分析了姿态指向抖动与聚束SAR成像质量指标的关系，推导了姿态指向稳定度与聚束SAR图像质量之间定量关系的解析表达式，为聚束模式星载SAR卫星总体分析和设计提供了理论依据。最后通过计算机仿真验证了分析的正确性。

| Abstract: | Attitude stability is a very important parameter for the platform design of Synthetic Aperture Radar(SAR) satellite.Based on the mathematical model of satellite attitude jitter and paired echo theory,a method quantitatively analyzing the relationship between spotlight SAR imaging quality and satellite attitude jitter was develop.The validity of theoretical results was confirmed by computer simulation. |
