Analysis and compensation for the attitude error of multi-channel spaceborne synthetic aperture radar
The effect of attitude control error on multi-channel spaceborne synthetic aperture radar (SAR) imaging is studied. Firstly, the mathematical model of multi-channel attitude control error is established. Then, based on the model, the quantificational relationship between the attitude error and SAR imaging parameters such as position of receiving antenna phase center, angle of control error, and grazing angle, is derived. Moreover, the influence on SAR imaging caused by attitude error is analyzed in detail. Based on the analysis, a high-efficiency and accuracy method of compensation is proposed. Finally, computer simulation prove the validity of the compensation method.
