Synthetic Aperture Radar

Synthetic Aperture Radar (SAR) is a technology used to create detailed images of landscapes from aircraft or satellites. It works by sending out radar signals and measuring the time it takes for the signals to bounce back after hitting the ground. By moving while collecting data, SAR can simulate a larger antenna (an "aperture"), which improves image resolution. This allows for clear images of terrain, even in poor weather or darkness. SAR is valuable for mapping, environmental monitoring, and disaster response, providing insights into changes in the Earth’s surface.
