| Summary: | The high flexibility and tight accuracy
requirements of today's spaceborne synthetic aperture radar (SAR) systems require
innovative technologies to calibrate and process the SAR
images. To perform accurate pattern correction during
SAR processing, an Antenna Model is used to derive the
multitude of different antenna beams generated by active
antenna steering. The application of such an Antenna
Model could be successfully demonstrated for the
TerraSAR-X mission, launched in 2007. The methodology
and the results of the inorbit verification with an achieved
accuracy of better than ±0.2 dB is reviewed in this paper
in detail showing its outstanding accuracy. |
