Synthetic Aperture Radar (SAR)

Synthetic Aperture Radar (SAR) is a remote sensing technology that uses radar signals emitted from a moving platform, like a satellite or aircraft, to create high-resolution images of Earth's surface. As it moves, SAR combines the radio waves reflected back from different points on the ground to simulate a large "antenna" or aperture, resulting in detailed images regardless of weather or lighting conditions. This ability to capture precise terrain details makes SAR valuable for applications like environmental monitoring, disaster assessment, and mapping, providing accurate data even through clouds or darkness.
