Compensation of Ionospheric Phase Scintillation of ALOS PALSAR Imaging

摘要：

　　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 PALSAR L1.0 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.
