Abstract

This paper presents a dual cancelled channel approach to the target detection and estimation with a digital beamforming radar. The proposed STAP (space-time adaptive processing) scheme is shown to yield comparable detection performance to previously known schemes and higher accuracy in the estimation of the target direction of arrival. Moreover, it has a lower computational cost, since it does not require the numerical maximization of a functional.
