| Abstract: | The beam space MUSIC algorithm is the most representative method of beam space high resolution Direction-of-Arrival （DOA）. The operation in beam space offers a number of advantages over the operation in element space, including reduced computational complexity and lower SNR resolution threshold. This paper addresses the problem of DOA of narrow-band emitter signals impinging on an antenna array, and a modified beam space MUSIC algorithm for high resolution array processing is presented. Simulation results show the improved algorithm reduces SNR resolution threshold. |
