“发现者Ⅱ”(Discoverer Ⅱ)联合计划办(JPO)于1998年底公布了天基雷达(SBR)第1阶段演示计划的建议申请书(RFP),该计划是由美空军、国防预研计划局(DARPA,前译为国防高级研究计划局)和国家侦察办联合提出的,旨在研制和演示一种具有大比例/高分辨率的地面移动目标指示(GMTI)、合成孔径雷达(SAR)图像能力以及数字化地形测绘标高数据(DT-ED)的天基雷达(SBR),以提供侦察、监视和精确的大地位置信息。
The Discoverer II Joint Program Office (JPO) announced a Proposed Application (RFP) for the Phase 1 Demonstration Project of Space Radar (SBR) at the end of 1998. This proposal was issued by the U.S. Air Force, the Defense Advanced Research Projects Agency (DARPA) and the National Reconnaissance Office to jointly develop and demonstrate a large-scale / high-resolution ground moving target indicator (GMTI), synthetic aperture radar (SAR) images Capabilities and digital terrain mapping elevation data (DT-ED) space-based radar (SBR) to provide reconnaissance, surveillance and accurate geostationary position information.
