This paper presents a simple method of the direction of arrival (DOA) estimation for the nonuniform linear array
which uses the spatial smoothing MUSIC technique.In the case of the same sensor number
this method which adopts appropriate array geometry arrangement can improve the resolvability of DOA estimation more obviously than the uniform linear array.It also overcomes the shortcoming of the ambiguity of DOA estimation and the poor quality of de correlation in the conventional nonuniform linear array.
