Abstract The effects on performance of the space-borne Synthetic Aperture Radar(SAR,) clue to antenna pattern and the beam steering are studied, especially emphasis on the ambiguities, the spatial resolutions and the signal to noise ratio. The directivity control and beam forming of active phased array are studied. Based on these studies, the phased array for the two swaths space-borne scan-SAR system is designed and simulated. Furthermore, the reliability of the phased array is studied and a high reliable design utilizing redundancy is proposed.
