在过去，持续散射体干涉测量（PSI）的应用主要是在缓慢（每年小于几厘米）的均匀运动的情况下。在本文中，我们展示了PSI如何允许使用TerraSAR-X重复观测对深部采矿进行相对快速（包括高达> 50 cm/年的速率）和不均匀运动的监测。为了实现这一点，PSI方法的一部分进行了调整，以研究的例子的特殊特性。除了所使用的方法和取得的结果的描述，误差的考虑和验证的结果与现场测量。
In the past, the application of Persistent Scatterer Interferometry (PSI) was primarily possible in the case of slow (less than a few centimeters per year) uniform movements. In this paper, we show how PSI permits the monitoring of relatively fast (including rates up to > 50 cm/year) and nonuniform movements using TerraSAR-X repeat observations over deep-level mining. To enable this, parts of the PSI methodology were adapted to the special characteristics of the example studied. Apart from a description of the methodology used and the result achieved, error considerations and a validation of the result with in situ measurements are included.
