radar imaging
Microwave terrain mapping
Radar imaging uses radio waves to create pictures of objects or terrain, particularly when visual observation is impossible.
Unlike cameras, radar can see through clouds, darkness, and foliage.
Satellites use radar imaging to map Earth's surface; aircraft use it to detect ground features in poor visibility.
The radar imaging revealed ancient roads beneath the jungle canopy.
