Change Detection in Dual Polarization Sentinel-1 Data With Wilks' Lambda

When the covariance matrix formulation is used for multilook polarimetric synthetic aperture radar (SAR) data, Wilks' Lambda can be change detection between acquisitions at two time points. We briefly describe theory dual polarization, diagonal only data. A case study illustrates technique on Sentinel-1 C-band data covering international Frankfurt Airport. successfully detect including direction of in sense that shows whether signal increases or decreases over time.
