Omnibus test for change detection in a time sequence of polarimetric SAR data 
Allan Aasbjerg Nielsen, Knut Conradsen, Henning Skriver

Abstract  Based on an omnibus likelihood ratio test statistic for the equality of several variancecovariance matrices following the complex Wishart distribution with an associated pvalue and a factorization of this test statistic, change analysis in a short sequence of multilook, polarimetric SAR data in the covariance matrix representation is carried out. The omnibus test statistic and its factorization detect if and when change(s) occur. The technique is demonstrated on airborne EMISAR Cband data but may be applied to Sentinel1, CosmoSkyMed, TerraSARX, ALOS and RadarSat2 or other dual and quad/fullpol data also.
