Improving EFA-STAP performance using persymmetric covariance matrix estimation

You are here

This paper deals with the estimation of the clutter covariance matrix in airborne radar space-time adaptive processing (STAP). Based on the persymmetry property, a novel STAP method referred to as persymmetric extended factored processing (Per-EFA) is derived, which can make a more intensive use
of the secondary data and improve the STAP performance in training-limited scenarios. Simulation results demonstrate the effectiveness of this method.
