Presents a technique to detect and correct phase errors appearing in interferometric
airborne synthetic aperture radar (SAR) systems due to the lack of precision in the
navigation system. The technique is based on a multisquint processing approach, ie by
processing the same image pairs with different squint angles we can combine the
information of different interferograms to obtain the desired phase correction. Airborne single-
pass interferometric data from the Deutsches Zentrum fu/spl uml/r Luft-und Raumfahrt (DLR) …
