The separability of active sonar signals in the presence of reverberation
Lan Ying · 2010
The separability of active sonar signals is the important factor for the application of blind source separation(BSS) to the signal detection in the presence of reverberation.Based on the sonar data model and the analysis of the source correlation function,a rule has been presented for judging the separability of the sonar data.It has been described that the reverberation data is separable when the sources have small correlation coefficient in most of time delays.The simulation data and trial data with two classical transmitting signals(CW and LFM) are used to verify the rule,and the result says that the separation of the reverberation data is possible when the LFM is the transmitting signal.
