Abstract

The complex Wishart distribution is used to describe synthetic aperture radar (SAR) data in the so-called covariance matrix representation. We give a test statistic for detection of differences between two instances in this distribution and an associated probability measure. Generated complex Wishart distributed covariance matrices are used to show that this test statistic and the probability measure in situations with no differences follow the expected distributions.
