A new method for joint DOA and FOA estimation using MUSIC algorithm

In this paper, a new algorithm with high-resolution is presented estimating simultaneously both the directions of arrival (DOA) and the source frequencies (FOA) based on the MUSIC algorithm. Some asymmetry is introduced to expand the array manifold matrix A (/spl theta/, f) and make possible the joint detection of DOA and FOA using 1D uniform linear-array (ULA). Finally, the simulation results are also introduced to demonstrate the high performance of the algorithm.
