在雷达星-1投入运行3年后,加拿大计划研制下一颗雷达成像卫星—雷达星-2,预计2001年底发射。主承包商为MDA公司。雷达星-2由轨道科学公司的平台和Spar宇航公司的合成孔径雷成构成,天线尺寸15m×1.5m。卫星重2.5 t,平均功率1 kW,峰值功率3 kW(只可持续18 min)。雷达采用电子扫描,工作频率5.3 GHz,按几种方式,分辨率可达3 m～100 m,成像面积为25 km~2～500 km~2,视场10～60°,扫描场1600 km。由于装有640片收/发
Three years after Radar Star-1 was put into operation, Canada plans to develop the next radar imaging satellite, Radar Star-2, which is expected to launch by the end of 2001. The main contractor for the MDA company. Radar Star-2 by the Orbital Science platform and Spar aerospace synthetic aperture Lei Cheng composition, antenna size 15m × 1.5m. Satellite weight 2.5 t, average power 1 kW, peak power 3 kW (sustainable only 18 min). The radar uses electronic scanning with a working frequency of 5.3 GHz. The resolution is up to 3 m to 100 m in several ways with an imaging area of 25 km to 2 to 500 km 2, a field of view of 10 to 60 ° and a field of 1600 km. With 640 receive / send
