Abstract :
A process using a combination of the spectral MUSIC algorithm with its variations root-MUSIC, beamspace MUSIC and beamspace root-MUSIC for determination of direction-of-arrival of wavefronts impinging on an array is proposed. Simulation results are presented, that illustrate the success of the process to determine the correct angles of signals arriving at the array sensors in a wide range of angles.
