A test statistic for equality of two complex variance-covariance matrices following the complex Wishart distribution with an associated probability of observing a smaller value of the test statistic is sketched. We demonstrate the use of the test statistic and the associated probability measure for change detection in both full and dual polarimetry synthetic aperture radar (SAR) data collected by the Danish EMISAR system.
