Abstract
In the Persistent Scatterer Interferometry relative height and deformation updates are estimated between nearby persistent scatterers (PSs). In practice, a reference network is established and the absolute values are estimated by integration. However, PSs can be mis-detected and relative measurements mis-estimated. As a consequence, the integration result depends on the integration path. Therefore, inconsistent measurements need to be eliminated. This paper presents our implemented integration technique which is based on a multithreaded Singular Value Decomposition. An advantage of our method is the straight forward error propagation assessment. As a result, the actual network can be improved by removing inaccurate point scatterers.
