摘要
合成孔径雷达干涉测量法(InSAR)是一种被广泛接受的监测地表形变的方法。这种方法在一些具有特定特征的地方应用非常成功,比如:有足够的散射体,坡度比较缓,植被变化比较慢等的地方。我们研究了两种不同的测量技术,结果表明他们能很好的测定我国四川郧阳县的山体滑坡,并且测定数据与通过地学测量法获得的数据相吻合。研究结果证明了合成孔径雷达干涉测量在山体滑坡和地壳表面运动的探测中具有非常大的潜力。
Synthetic Aperture Radar Interferometry （InSAR） is an established method for the detection and monitoring of earth sur- face processes. This approach has been most successful where the observed area fulfills specific requirements, such as sufficient backscattering, flat slope grad- ients or very slow changes of vegetation. We investigated the capability of two different InSAR tech- niques and achieved good results for the recognition of landslides in YunYang that compared well with geodetic derived movement rates. This demonstrates the strong potential of SAR Interf- erometry for the detection of landslides and earth surface movements.
