The YAOGAN-18 satellite, also known as Yaogan Weixing 18, was launched on October 29, 2013, from the Taiyuan Satellite Launch Center using a Chang Zheng 2C launch vehicle. Operated by ZZB and manufactured by SAST, this Earth observation radar satellite has dimensions of 2 meters in length, 1.5 meters in diameter, and a span of 4 meters when its solar arrays are deployed. The spacecraft has a dry mass of 2000 kilograms and is equipped with SAR (Synthetic Aperture Radar) for mission purposes. Its shape is described as a box with two panels and it uses two deployable solar arrays along with batteries for power generation. The satellite's RCS (Reflectivity Coefficient Surface) value is recorded at 3.6009, indicating its reflective surface properties in space.
