Change detection in multi-temporal dual polarization Sentinel-1 data

Allan Aasbjerg Nielsen, Morton John Canty, Henning Skriver, Knut Conradsen

AbstractBased on an omnibus likelihood ratio test statistic for the equality of several variance-covariance matrices following the complex Wishart distribution with an associated p-value and a factorization of this test statistic, change analysis in a time series of 19 multilook, dual polarization Sentinel-1 SAR data in the covariance matrix representation (with diagonal elements only) is carried out. The omnibus test statistic and its factorization detect if and when change occurs.
