Synthetic Array Radar
Abstract
The main aim of this chapter is to reveal the function of the synthetic array radar (SAR). Normally, this radar is used to map ground features and terrain. It is also known in the literature as synthetic aperture radar. SAR can be an acronym for both. SAR systems can be designed with capabilities to differentiate using dimensions from few centimeters to hundreds of meters, depending on if the purpose is to map out a military installation—an urban area—or the contours of a mountain range. SAR radar is able to effectively create a very long antenna, hundreds of meters, using the motion of the aircraft. The radar is pulsed along this flight path, and the returns are digitally combined, to be able to view ground ...
