Synthetic Aperture Radar (SAR)
Synthetic Aperture Radar (SAR) : A radar system which correlates the echoes of signals emitted at different points along a satellite's orbit or an airplane's flight path. The highest resolution achievable by such a system is theoretically equivalent to that of a single large antenna as wide as the distance between the most widely spaced points along the orbit that are used for transmitting positions. In practice, resolution will be limited by the radar receiver's signal-processing capability or by the limited coherence of the radio signal emitted by the radar transmitter
