Title
TerraSAR-X Antenna Calibration and Monitoring Based on a Precise Antenna Model
Abstract
The high flexibility and tight accuracy requirements of modern spaceborne synthetic aperture radar (SAR) systems re- quire innovative technologies to calibrate and process SAR images. To perform accurate pattern correction during SAR processing, an antenna model can be used to derive the multitude of different an- tenna 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 in-orbit verification with an achieved accuracy of better than ±0.2 dB are reviewed in this paper in detail, showing its outstanding accuracy. Additionally, the results of the antenna pattern long-term monitoring are described, pointing out the high stability of the system.
