Abstract: The space race gave birth to a remote sensing technique known as synthetic aperture radar (SAR) that could be used for everything from tracking militaries to mapping the surface of the moon, all the while disguising its true value — global deformation monitoring. This is the story of how a little-known technique has evolved into a system that provides a constantly updating archive of millimeter-accuracy spatial data covering every part of our planet. Seeing through clouds and darkness, this artificial intelligence (AI)-powered system lives in your browser, but is a key to the future of infrastructure monitoring.
