Abstract :
The paper presents a Kalman filter based data fusion approach to unwrap and simultaneously filter the phases of interferometric SAR (InSAR) images. Furthermore phase slope information extracted from the power spectral density of the interferogram is incorporated by the Kalman filter giving rise to data fusion concepts
