DIRECTION FINDING FOR DIVERSELY POLARIZED SIGNALS USING POLYNOMIAL ROOTING

We present a direction finding algorithm for diversely polarized array s that is based on polynomial rooting. Using polynomial rooting instea d of search reduces significantly the computational requirements of th e algorithm and enhances resolution. The basic method is limited to li near uniformly spaced arrays. However, using an interpolation techniqu e, the algorithm is extended to a larger class of arrays. The performa nce of the proposed algorithm is analyzed. Computer simulations are us ed to demonstrate the performance of the new technique and to verify t he performance analysis.
