The Effect of Surface Scattering On Ifsar Baseline Decorrelation

Across-track Synthetic Aperture Radar Interferometry is an emerging technique for Earth monitoring capable to generate high-resolution Digital Elevation Models. The ability to achieve such mission depends on the correlation of the signals received by the two antennas and used to generate the interferometric fringes. In this paper we formulate the baseline decorrelation due to antennas spatial diversity to include the effect of surface scattering.
