Abstract

Among direction-of-arrival (DOA) estimation algorithms with narrow-band sensor arrays, eigen-based decomposition algorithms are hard to meet the demand of real-time signal processing because of the huge computation. To solve the problem of computational load, we propose and analyze a fast and high-precision DOA estimation algorithm based on spatial Fourier coefficient iterative interpolation. This method is shown to achieve identical asymptotic performance by constructing and interpolating the modified value at the adjacent bins of the maximum in spatial spectrum. An optimization method to reduce the iteration times is also given. The simulation results show that the proposed algorithm may achieve the same estimation precision as MUSIC in certain condition without the huge computation.
