  • METHOD AND APPARATUS FOR CORRECTING IONIC DISTORTION OF SATELLITE RADAR INTERFEROGRAM
    Publication number: 20150369913
    Abstract: An apparatus and method for correcting the ionospheric distortion of an SAR (Synthetic Aperture Radar) interferogram are disclosed herein. The apparatus includes a multiple aperture SAR interferometry (MAI) interferogram generation unit, a transformed MAI interferogram generation unit, an ionospheric distortion interferogram generation unit, and a corrected SAR interferogram acquisition unit. The multiple aperture SAR interferometry (MAI) interferogram generation unit generates a multiple aperture SAR interferometry (MAI) interferogram using an SAR interferogram. The transformed MAI interferogram generation unit generates a transformed MAI interferogram representative of the azimuth direction derivatives of ionospheric distortion phases using the phases of the MAI interferogram. The ionospheric distortion interferogram generation unit generates an ionospheric distortion interferogram using the transformed MAI interferogram.
