Abstract
This paper is focused on the polarimetric change detector (PCD) based on perturbation filters already developed by the authors. The highlight of the PCD is its independence of the overall amplitude of the coherence matrix (scaling factor), focusing exclusively on the polarimetric information. Here, the relationship between the PCD and the polarimetric and interferometric (Pol-InSAR) coherence is investigated. Many Pol-InSAR algorithms are based on the coherence operator, therefore such parameterisation would ease the process of setting the detector threshold. The methodology is tested using E-SAR AgriSAR, L-band quad polarimetric data, showing agreement with the observed changes and the actual interferometric coherence.
