Brief Analysis on the Development and Application of Spaceborne SAR

  • 摘要: 星载合成孔径雷达(Synthetic Aperture Radar, SAR)作为一种主动式微波成像传感器,能够不受天气、气候以及光线的影响,可以全天时、全天候地成像,因此,星载合成孔径雷达已发展成为一种不可或缺的对地观测工具。随着技术的进步,未来星载SAR将实现高分辨率宽测绘带、低成本、小型化、多基多模式微波成像,并具有地面运动目标指示的能力,在最小的成本下获得最丰富的地物信息。这迫切需要星载SAR系统在新模式、新体制、新技术方面取得重大突破。该文将围绕星载合成孔径雷达技术发展现状及未来趋势展开论述。
