Synthetic aperture radar (SAR) is a remote sensing technology that uses radar signals to generate high-resolution images of the Earth's surface. SAR systems use the motion of the radar antenna to simulate a large antenna aperture, allowing for the creation of detailed images even from a moving platform such as an aircraft or satellite. SAR is widely used for applications such as monitoring land cover change, mapping of urban areas, and disaster response. The technology can be used in a variety of environmental and geological applications, as well as for military and defense purposes.
