Analysis of Ground Based SAR Images Acquired In A Small Urban Area Using Diverse Polarization Configurations

Abstract

A Ku band-terrestrial radar interferometer with different polarization combination capability, including left and right circular polarization (CP), has been used to investigate the potential of different co-polar and cross-polar acquisitions for Terrestrial Radar interferometry (TRI), aiming at improving the monitoring of landslides in semi-urban areas. After some preliminary tests carried out to verify the responses of simple targets, Ground Based SAR images acquired in a test area affected by a landslide have been analyzed. The study of how different polarization combinations affect coherence and amplitude dispersion of natural media and man-made structures has been carried out to evaluate the potentialities of the different polarization observations, aiming at easing the identification of stable scatters.
