Abstract

Interpolation array approach based on Taylor series fitting for arbitrary geometry array is developed in this paper. As the steering vector is a function of direction-of-Arrival (DOA), Taylor series fitting for the steering vector is conducted within an angle range, and the steering matrix is decomposed into a coefficient matrix multiplying by a Vandermonde structure vector bearing the DOA information. Moreover, the coefficient matrix is calculated by the least squares method. Results show that the proposed approach has a better DOA estimation performance over the traditional interpolation array technique under uncorrelated and correlated signal conditions.
