Definition
SAR. Synthetic aperture radar – a side-looking imaging radar on a moving platform that exploits the Doppler history of received signals to synthesize the effect of a very long antenna (aperture) with a corresponding high spatial resolution in flight (azimuth) direction.
Interferometry. In this context, the analysis of amplitude and phase differences between corresponding pixels of two complex SAR images of the same scene, acquired from slightly different antenna locations or at slightly different times.
Interferometric SAR (InSAR). A SAR with two (or more) antennas for interferometry.
Along-track interferometry (ATI). Interferometric analysis of SAR images acquired by two antennas with a distance (baseline) in flight direction, which scan the scene at slightly different times. Phase differences are proportional to Doppler shifts and, thus, line-of-sight velocities.
Cross-track interferometry (XTI). Interferometric analysis of SAR images acquired by two antennas with a...
