Change detection in a time series of polarimetric SAR data 
Knut Conradsen, Allan Aasbjerg Nielsen, Henning Skriver

Abstract  A test statistic for the equality of several variancecovariance matrices following the complex Wishart distribution with an associated probability of finding a smaller value of the test statistic is introduced. Unlike tests based on pairwise comparisons between all temporally consecutive acquisitions the new omnibus test statistic and the probability measure successfully detects change in two short series of L and Cband polarimetric EMISAR data. 
Keywords  Complex Wishart distribution, pairwise test statistic, omnibus test statistic.
