Abstract :
Introduces the concepts of blind source separation and independent component analysis. We show how they can be applied to the automatic estimation of ground subsidence and atmospheric disturbances on a series of interferograms. Finally we show some results obtained on realistic simulated data which demonstrate the advantages of this approach.
