Solution

The unique information content in SAR (Synthetic Aperture Radar) data is the structure and moisture of the land surface. SAR is a type of imaging radar in which the relative movement of the antenna and the target is utilized to provide finer spatial resolution. This is achieved through the use of radar antenna's motion to simulate a system much larger than the actual antenna. SAR is capable of high-resolution remote sensing, independent of flight path, and is widely used in geoscience applications. It can provide cross-sectional profiles and reveal detailed structure at the land surface.

A radar signal contains amplitude and phase information. is the strength of the radar response and is the fraction of one complete sine wave cycle (a single SAR wavelength). The phase of the SAR image is determined primarily by the distance between the satellite antenna and the ground targets.A satellite SAR can observe the same area from slightly different look angles. This can be done either simultaneously (with two radars mounted on the same platform) or at different times by exploiting repeated of the same satellite. The distance between the two satellites (or orbits) is called .
