Abstract

Direction of Arrival (DOA) estimation using antenna arrays is an important problem for combating jamming in GPS, as accurate DOA estimates lead to better interference suppression. In this paper, we improve the estimation DOA accuracy when the true incident angles are off the discretised sampling grid points. We propose a bisection interpolation method based on MUSIC pseudo-spatial spectrum coefficients. The proposed method can be applied to multiple uncorrelated sources in the field of view without any constraints on the antenna array shape. For coherent sources, both beamspace transformation and spatial smoothing are utilised to decorrelate the signals for uniform circular arrays, with sufficient number of antennas, prior to dichotomous search. Both simulated and experimental results validate the effectiveness and efficiency of the proposed algorithm.
