摘要: 該文從雷達工作模式、模糊度、分辨率及信噪比等幾個方面研究了星載合成孔徑雷達的有源相控陣天線波束調(diào)節(jié)方式和波束賦形特點,設計了一種適合于二條帶高分辨率掃描模式星載合成孔徑雷達的有源相控陣天線,該文還研究了有源相控陣天線的可靠性問題,提出一種利用冗余設計提高天線可靠性的方案。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.
