| 摘 要： | 分别选用两景Radarsat-2和TerraSAR-X数据，应用子带干涉技术获取夏威夷火山国家公园及其附近区域的沉降量，并将其与偏移跟踪技术结果进行对比，证明了子带干涉技术的地表形变监测能力，且分辨率越高、带宽越宽的TerraSAR-X数据得到的监测精度越高。用两景PALSAR数据，应用子带干涉技术获得唐洞煤矿地表方位向位移，与同期GPS监测数据进行对比，进一步验证了子带干涉技术的形变监测能力。

| 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. |
