Abstract

In recent years persistent scatterer radar interferometry (PS-InSAR) has proven to be a powerful remote sensing technique to measure deformation of the Earth’s crust—such as landslides— with an accuracy of a few millimeters. However to ensure a PS-InSAR processing with useable results, a stack containing at least 15 to 50 radar images is required. This high amount of radar images is a very important cost factor when applying this method. In this paper we present two methods for estimating the density of scatterers (possible persistent scatterers (PS)) prior to the radar recording of the area of interest. The goal of this scatterer estimation is to find out, whether the scatterer density of a certain landslide is high enough for PS-InSAR processing, or whether artificial scatterers, like corner reflectors, are necessary.
