摘要

利用先进陆地观测卫星(ALOS)搭载的相控阵l波段合成孔径雷达(PALSAR)数据，给出了电离层相位闪烁的补偿方法。相位闪烁基于多相屏理论生成，并添加到PALSARL1.0数据(未聚焦的原始数据)中。然后应用相位梯度自动对焦(PGA)来消除相位失真。仿真结果表明，补偿后电离层相位闪烁的影响明显消除。

Compensation of Ionospheric Phase Scintillation of ALOS PALSAR Imaging

By using the data of Phase Array L-band Synthetic Aperture Radar (PALSAR) on board Advanced Land Observing Satellite (ALOS), this paper shows the compensation of ionospheric phase scintillation. The phase scintillation is generated based on the multiple phase screen theory and added into the PALSARL1.0 data (unfocused raw data). The Phase Gradient Autofocus (PGA) is then applied to remove the phase distortion. Simulations show that after compensation, the effects of ionospheric phase scintillation is obviously removed.
