The mountain is around 80 kilometers long, some 10-20 kilometers wide. Its tallest peak has 2747 meters.
Vegetation on the mountain includes crops up to around 1000 meters, forests up to 1700 meters, and above that lie high pastures which encompass around 550 square kilometers. This mountain is most known as the origin of the dog breedŠarplaninac which was bred on these pastures.
The Sara National Park is in the territory of the Autonomous Province of Kosovo and Metohija and it spreads on 38,000 hectares, on the nothern slopes of Sar Mountain. What this national boasts in particular are the endemic relict Macedonian pine and white-bark pine, as well as the Alpine rose. As for game, this is the habitat of the lynx, bear, chamois and other species.
A locality called "Gine voda" is special attraction because the white-bark pine, Macedonian pine, skotch pine, spruce, sycamore... are represented there all on a small area.
The Sara National Park abounds in streams and small rivers and it spreads in the municipalities of Urosevac, Suva Reka, Kacanik and Prizren.
When a spaceborne SAR looks down and to the side toward a steep mountain, many objects on the mountain's facing slope may appear to be located at the same distance from the spacecraft.
SAR illumination is much like solar illumination, in that it also has difficulty reaching the back side of a mountain.
Since SAR images are based around distance, the "near range" side of the image is the side closest to the satellite, whereas the "far range" side of the image is the side farthest from the satellite.
Synthetic Aperture Radar (SAR) takes advantage of the Doppler history of the radar echoes generated by the forward motion of the spacecraft to synthesise a large antenna, enabling high azimuthal resolution in the resulting image despite a physically small antenna, as shown is figure1.6.
SAR is a coherent, active, microwave imaging method that improves natural radar resolution by focusing the image through a process known as synthetic aperture processing.
Because the signals received by a SAR system are recorded over a long time period, the system translates the real antenna over a correspondingly long distance, which becomes the effective length of the antenna.
