摘要: 该文从雷达工作模式、模糊度、分辨率及信噪比等几个方面研究了星载合成孔径雷达的有源相控阵天线波束调节方式和波束赋形特点,设计了一种适合于二条带高分辨率扫描模式星载合成孔径雷达的有源相控阵天线,该文还研究了有源相控阵天线的可靠性问题,提出一种利用冗余设计提高天线可靠性的方案。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.
