本文指出了下一代多种模式空基SAR/ISAR(合成孔径雷达/逆合成孔径雷达)系统的一些有关可行性分析的初步结果。正如当前对于未来遥感应用的设计一样,下一代SAR系统的关键在于有源相控阵天线。在此天线技术基础上,讨论了一些新的工作模式,这些工作模式,目前甚至到ERS—l时代,从空中向地面观测时也还是不能用上的。它们包括:·宽刈(swath)~(··)/中等分辨率的SAR模式·窄刈/高分辨率的SAR模式·斜视SAR模式·超分辨力聚束照射(Spotlight)/多波束模式·MTI(动目标显示)/ISAR模式
This paper points out some preliminary results about the feasibility of next generation multi-modal space-based SAR / ISAR (Synthetic Aperture Radar / Inverse Synthetic Aperture Radar) systems. Just as current design for future remote sensing applications, the key to the next generation of SAR systems is active phased array antennas. Based on this antenna technology, some new working modes are discussed. These working modes can not be used even when viewed from the air to the ground at present even to the ERS-1 era. They include: · Swath - (··) / Moderate Resolution SAR Modes · Narrow Mast / High Resolution SAR Modes · Strabismic SAR Modes · Spotlight / Multibeam Modes · MTI (Moving Target Display) / ISAR mode
