    abstract     = "Based 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 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} {L-}band data but may be applied to Sentinel-{1,} Cosmo-SkyMed, TerraSAR{-X,} {ALOS} and RadarSat-2 or other dual- and quad/full-pol, and even single-pol data also."
