Abstract :
Large datasets of satellite SAR missions dedicated to deformation monitoring will require intensive and dedicated interferometric processing techniques. Decorrelation effects will prevent simple processing approaches, but optimal algorithms are computationally intensive. This paper shows results of a novel efficient algorithm that aims at exploiting scatter component that are stable over time, without being isolated point targets. The concept is proved valid for simulated data and limited examples in X-band and L-band.
