Synthetic Aperture Radar Sub-Band Interference Technique and Its Application
Abstract A pair of Radarsat-2 and TerraSAR-X were employed to monitor the change of Hawaii volcano national park and its surrounding areas. Compared with the results obtained by offset-tracking technology, this fully demonstrates the ability of sub-band interferometry in deformation monitoring. In addition, comparing deformation obtained by the two kinds of data, the results show TerraSAR-X, with its higher resolution and wider bandwidth, can get more accurate results. Then the sub-band interferometry technology is applied to a pair of PALSAR of mine of Tangdong, to extract the azimuth deformation. Compared with GPS monitoring data obtained in the same time, it further validates ability of sub-band interferometry in deformation monitoring.
