Abstract :
The present communication is concerned about the use of synthetic aperture radar (SAR) images obtained by processing raw data and reference function both quantized at one bit (Signum Coding) for topographic mapping in interferometric SAR processing. In particular it is shown that in an actual cases relative to a spaceborne (ERS-1) missions, this technique provides two dimensional phases patterns (before and after phase unwrapping) very close to the ones obtained by using conventionally processed images
