Abstract
For monitoring nuclear sites, the use of Synthetic Aperture
Radar (SAR) imagery shows essential promises. Unlike optical
remote sensing instruments, radar sensors operate
under almost all weather conditions and independently of
the sunlight, i.e. time of the day. Such technical specifications
are required both for continuous and for ad-hoc,
timed surveillance tasks. With Cosmo-Skymed, TerraSARX
and Radarsat-2, high-resolution SAR imagery with a
spatial resolution up to 1m has recently become available.
Our work therefore aims to investigate the potential of
high-resolution TerraSAR data for nuclear monitoring. This
paper focuses on exploiting amplitude of a single acquisition,
assessing amplitude changes and phase differences
between two acquisitions, and PS-InSAR processing of an
image stack
