Abstract :
It can improve both accuracy and reliability of derived DEMs by combining multi-baseline InSAR data, more accurate height information can be derived from InSAR data with longer baseline and less difficulty can be met with shorter baseline. In order to study technique of multi-baseline InSAR, a simulation algorithm for interferograms of multi-baseline InSAR was proposed. It was based on boresight imaging model, and so F.Leberl formula was applied to establish relations between pixels and ground points. The interferometric phases were calculated with different baselines by iterative method. The DEM derived from SIR-C/X-SAR data was used in experiment, and interferograms with different baselines were simulated successfully.
