摘要： 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. The corrected SAR interferogram acquisition unit acquires a corrected SAR interferogram by eliminating the generated ionospheric distortion interferogram from the SAR interferogram.
摘要翻译：本文公开了一种用于校正SAR（合成孔径雷达）干涉图的电离层失真的装置和方法。该装置包括多孔径SAR干涉测量（MAI）干涉图生成单元，变换的MAI干涉图生成单元，电离层失真干涉图生成单元和经校正的SAR干涉图采集单元。多孔径SAR干涉测量（MAI）干涉图生成单元使用SAR干涉图生成多孔径SAR干涉测量（MAI）干涉图。变换的MAI干涉图生成单元使用MAI干涉图的相位生成代表电离层失真相位的方位角方向衍生的变换的MAI干涉图。电离层畸变干涉图生成单元使用转换的MAI干涉图产生电离层失真干涉图。经校正的SAR干涉图获取单元通过从SAR干涉图中消除所产生的电离层失真干涉图来获取校正的SAR干涉图。
