What is Synthetic Aperture Radar

Synthetic Aperture Radar (SAR) is a type of radar that uses radio waves to create high-resolution images of the Earth's surface. It works by transmitting a signal from an antenna on a moving platform, such as a satellite or airplane, and then receiving the reflected signal from the ground. By combining the signals received from multiple locations, SAR can create a detailed image of the terrain, even in areas where traditional optical sensors may be hindered by cloud cover or darkness. SAR is commonly used for mapping, environmental monitoring, and military reconnaissance.
