Paper Abstract

A direction-finding algorithm employing the technique of array manifold interpolation is proposed for the estimation of directions-of-arrival of multiple narrow-band sources. The algorithm is formulated by applying array manifold interpolation to an ESPRIT-type method. As a result, a virtual array can be interpolated from the data collected from a real array, thereby eliminating the need for two identical arrays as in ESPRIT. Moreover, only a single interpolation matrix for the entire field-of-view is required, thus significantly reducing the computational load of the sector-divided interpolation scheme. Simulation results are provided to show the effectiveness of the proposed algorithm.
