摘要
先进复合材料具有重量轻、热稳定、E?(ρ.α)高等一系列优点,大型复合材料SAR(合成孔径雷达)天线已成功应用于国外在轨的星载相控阵雷达系统中。介绍了先进复合材料在SAR天线中的应用现状,分析了在星载雷达领域中的关键应用和设计技术,探讨了先进复合材料空间应用技术发展趋势。
Advanced composites have many good properties, such as low weight , thermal stability, high E/（ρ,α）. Large SAR（ synthetic aperture radar ）antenna made of composite has been used overseas as orbital spaceborne phased array antenna. This paper introduces present situation of application of composites in SAR antenna , analyzes their key applications and design technology in spaceborne radar system, and discusses the development trend of composites application to spaceborne radar.
