Abstract: We consider the problem of estimating high-dimensional covariance matrices of K -populations or classes in the setting where the sample sizes are comparable to the data dimension. We propose ...

To tackle the issue of space-time adaptive processing (STAP) performance degradation caused by inaccurate estimation of the clutter covariance matrix (CCM) with limited sample support, a ...
