A Comparison Between SqueeSAR and CAESAR for the Detection of Decorrelating Scatterers
Monitoring displacements with interferometric synthetic aperture radar involves, as final processing stage, the detection of persistent/distributed scatterers. Filtering and multilook is adopted to improve the detection performances in non-urbanized areas, where dominant point scattering mechanisms are less frequent. SqueeSAR and CAESAR based detectors were already compared in [1] under the hypothesis of weak and fully correlated scattering. In this work we extend the comparison to account for the presence of scattering decorrelation. The comparison is carried out by analyzing simulated data as well as data acquired by the COSMO-SkyMed constellation. In both cases the detection based on CAESAR outperforms the one based on SqueeSAR.
