%X 平流层飞艇具有驻空高度高且时间久、覆盖范围广、使用效费比高等特点，在侦察监视等领域应用前景广阔。结合平流层飞艇平台特性，分析平流层飞艇合成孔径雷达（Synthetic Aperture Radar, SAR）与机载SAR的异同；针对平流层飞艇SAR的脉冲重复频率冗余及大振幅低频率运动误差，提出优化方案，并开展仿真分析验证。仿真结果表明所提优化运动补偿方法能够有效消除平流层飞艇运动误差影响。</br>The stratospheric airship has the potential as large observation area, long drift time, and better efficiency. It is expected in many different applications, such as reconnaissance and surveillance. The imaging difference between the stratospheric airship SAR (synthetic aperture radar) and the airplane SAR was compared. Aimed at the redundant pulse repetition frequency and the large-amplitude low-frequency trajectory deviation, an optimization scheme was proposed and verified by simulation. The simulation result shows that the proposed optimized motion compensation method can eliminate the influence of motion error for the stratospheric airship effectively.
