Specifically, a type called synthetic aperture radar, which works day and night, and through clouds.

具体来说，就是一种合成孔径雷达，它可以夜以继日地工作，还可以穿越云层工作。

The " synthetic aperture" of SAR satellites describes an important advance.

SAR卫星的“合成孔径”描述了一个重要的进步。

The technology capturing these images, Synthetic aperture radar—also known as SAR—is booming.

捕获这些图像的技术，即合成孔径雷达（也称为 SAR）正在蓬勃发展。

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。
