| contents | In this paper, the performance of non-uniform spacing of sensors is evaluated for the MUSIC algorithm which estimates the direction of arrival (DOA) of a narrowband plane wave impinging on an array of sensors. Unlike uniform sensor spacing arrangement, where sensors are equidistant (equal to half the wavelength), we consider non-uniform spacing for the arrangement of sensors, where the distance between consecutive sensors increases progressively. We observe that the non-uniform sensor spacing configuration (with lesser number of sensors) can provide similar or better accuracy in DOA estimation compared to uniform sensor spacing configuration despite more number of sensors at identical array length. |
