The satellite is also the world's first high-orbit synthetic aperture radar (SAR) satellite entering the project implementation stage, and it will be mainly used to provide remote sensing information services.

该卫星也是世界上第一颗进入项目实施阶段的高轨道合成孔径雷达（SAR）卫星，它将主要用于提供遥感信息服务。

Synthetic aperture radar (SAR) satellites, which send out radar pulses rather than relying on ambient light, would pick up the metallic reflections of heightened vehicle activity.

合成孔径雷达（SAR）卫星发出雷达脉冲而不是依赖环境光，它会捕捉到车辆活动增强时产生的金属反射。
