Abstract :
The MUSIC algorithm for determination of direction-of-arrival of wavefronts impinging on an array is analyzed. Simulation results are presented, that illustrate the behaviour of the algorithm for incoherent and coherent signals arriving at the array sensors in a wide range of angles by using a preprocessing technique. Moreover, the response of the algorithm for signals arriving at close angles is examined, in connection with the signal-to-noise ratio (SNR) of the signal and the sample rate
