Performance evaluation of the modified FBLP method for angle of arrival estimation using real radar multipath data

The paper presents the results of a detailed evaluation of the modified forward-backward linear prediction (FBLP) method used for angle of arrival estimation in a low-angle tracking radar environment. The results are based on real radar data pertaining to an angular separation of less than one standard beamwidth between the direct and image components impinging on the radar antenna. The results confirm the superior performance of this method compared to a conventional FFT beamformer. The paper also includes a brief review of the modified FBLP method.
