| Abstract: | The estimation of the direct of arrival(DOA) is one of the key technologies in smart antenna system.Through the discussion of traditional DOA estimation based on MUSIC algorithm,a method of DOA estimate based on MUSIC algorithm with spatial smooth technology was proposed.The result shows that the incisive spectrum peak and the high resolution for coherent source are obtained by using the MUSIC algorithm with spatial smooth technology. |
