Performance analysis of non uniform linear arrays using MUSIC algorithm for under water communication

Abstract

This paper presents the performance analysis of Uniform Linear Array (ULA) and Non Uniform Linear Arrays (NULAs), using Multiple SIgnal Classification (MUSIC) algorithm for Direction-Of-Arrival (DOA) estimation. Non Uniform Linear Arrays are applied to Under Water Communication by constructing a Non Uniform Linear SONAR Array. Another variation of NULA, called the Nested Arrays is compared with ULA in terms of the Degrees of Freedom. The considered Non Uniform Linear SONAR and Nested Arrays are compared in terms of resolution and Array length. MUSIC algorithm is simulated using MATLAB.
