 Synthetic aperture radar

Synthetic Aperture Radar (SAR) is a form of radar technology used to create high-resolution images of landscapes, objects, and surfaces. It operates by emitting microwave signals from a moving platform, such as an aircraft or satellite, and then capturing the reflected signals from the target area. The term "synthetic aperture" refers to the technique employed to simulate a larger antenna or aperture by using the motion of the radar system.
