Abstract :
This paper presents a technique to calibrate interferometric airborne SAR images based on a multisquint processing approach, i.e., by processing the same image pairs with different squint angles we can combine the interferograms to obtain the desired phase correction. Airborne single-pass interferometric data from the DLR´s E-SAR is used to validate the method.
