Comparative Analyses Of Multi-Frequency PSI Ground Deformation Measurements

In recent years many new developments have been made in the field of SAR image analysis. The wider diversity of available SAR imagery gives the possibility of covering wide ranges of applications in the domain of ground motion monitoring for risk management and damage assessment. The work proposed is based on the evaluation of differences in ground deformation measurements derived from multi-frequency PSI analyses. The objectives of the project are the derivation of rules and the definition of criteria for the selection of the appropriate SAR sensor for a particular type of region of interest. Key selection factors are the satellite characteristics (operating frequency, spatial resolution, and revisit time), the geographic localization of AOI, the land cover type and the extension of the monitoring period. All presented InSAR analyses have been performed using the Stable Point Network (SPN) PSI software developed by Altamira Information [1].
