Abstract :
This paper presents an extension to interferometric SAR (InSAR), known as multi-baseline InSAR. The technique is based on the use of N>2 SAR imaging flight paths to synthesise an aperture in the normal-to-slant-range (nsr) direction. This leads to the generation of digital elevation models with improved ground-range resolution and elevation accuracy as well as the ability to resolve scatterers in the nsr direction
