This paper presents a study of differential AoA (Angle-of-Arrival) based 2D localization method utilizing FM radio signals (88&#x2009;MHz&#x2013;108&#x2009;MHz) as Signals of Opportunity (SOP). Given prior knowledge of the transmitters&#x2019; position and signal characteristics, the proposed technique utilizes triangulation to localize receiver&#x2019;s 2D position. Dual antenna interferometry provides the received signals&#x2019; AoA required for triangulation. Reliance on precise knowledge of antenna system&#x2019;s orientation is removed by utilizing differential Angle of Arrivals (dAoAs). The 2D localization accuracy is improved by utilizing colocated transmitters, a concept proposed in this paper as supertowers. Analysis, simulation, and ground-based experiments have been presented; results showed that when the SNR (Signal-to-Noise Ratio) is higher than 45&#x2009;dB, the proposed method localizes the receiver&#x2019;s 2D position with an error of less than 15&#x2009;m.
