Abstract

SONAR is one of underwater communication by using acoustic wave which having smaller attenuation value in underwater than others wave. However, SONAR received mixing information from the source caused by noise from ship, offshore activity and seismic noise. Therefore, in this paper we propose a method using Independent Component Analysis (ICA) to separate the mixing signal to get the desired signal. Sound source separation is performed at mini underwater test tank in Vibration and Acoustics Laboratory using the same number of source and sensor configuration. The variables are varied based on salinity, temperature and sensor displacement changes. The separation process was carried out using TDICA, FDICA, and MSICA methods. From the mixed sound recording results obtained the best separation results using FDICA and MSICA methods for each variable change. The average MSE score was …
