doi:10.13474/j.cnki.11-2246.2017.0261

Abstract

Abstract: Joint scatterers InSAR is the second-generation time-series InSAR technology, comprised of three technical procedures:building a joint scatterers signal model, performing a goodness-of-fit test, and conducting a spatial adaptive filtering. Based on one-dimensional KSTEST inference, the essay advances method of non-parametric goodness-of-fit test based on joint scatterers. In comparison with the results of conventional multi-temporal InSAR, the testing data based on the new methods have attested to an effective elevation in the spatial density of deformation monitoring points and a further improvement in the deformation monitoring capacity.

Key words: joint scatterers, InSAR, distributed scatterers, goodness-of-fit test, KSTEST, multi-temporal InSAR
