Synthetic aperture radar is a form of radar in which sophisticated post-processing of radar data is used to produce a very narrow effective beam. In SAR imaging, microwave pulses are transmitted by an antenna towards the earth surface. The microwave energy scattered back to the spacecraft is measured. The SAR makes use of the radar principle to form an image by employing the time delay of the backscattered.
