Synthetic Aperture Radar (SAR) imaging is a remote sensing technology used to create high-resolution images of the Earth's surface. It works by transmitting microwaves towards the target area and capturing the reflections that bounce back. By processing these reflections, SAR imaging can generate detailed images that are useful for a variety of applications, including mapping, monitoring land use changes, detecting natural disasters, and analyzing vegetation cover. SAR imaging is particularly valuable because it can produce images in all weather conditions and even in darkness, making it a versatile tool for Earth observation.
