Target DoA estimation in passive radar using non-uniform linear arrays and multiple frequency channels [PDF]

, 2018
In this paper we present a robust approach for target direction of arrival (DoA) estimation in passive radar that jointly exploits spatial and frequency diversity. Specifically we refer to a DVB-T based passive radar receiver equipped with a linear array
