WebInterferometric Synthetic Aperture Radar (InSAR), or SAR Interferometry, is the measurement of signal phase change between two images acquired over the same area, at different time. When a point on the ground moves, the distance between the sensor and the point changes and so the phase value recorded by the sensor will be affected too. WebSAR’s ability to produce relatively fine azimuth resolution differentiates it from other radars. To obtain fine azimuth resolution, a physically large antenna is needed to focus the …
