Abstract

In this paper, we investigate a system of spatial multiple sensor arrays in an acoustic field in order to evaluate the parameters of the spatial signal and the location of the signal source. A uniform linear array and a periodic scanning system is considered. The spatial spectrum that expresses the signal distribution in the space from all directions to the receiver is determined. We evaluate the efficacy of direction of arrival (DOA) based on Multiple Signal Classification (MUSIC) algorithm estimation method for low frequency range when the number of array elements, the number of snapshots (i.e. the number of samples), SNR and element spacing are parameters in numerical simulation. The simulation results review all factor affecting the accuracy of estimation.
