An Overview of Array Signal Processing and Beam Forming Techniques

Abstract: For use as hydrophones, projectors and underwater microphones, there is always a need for calibrated sensors. Overview of multi path and effect of reflection on acoustic sound signals due to various objects is required prior to finding applications for different materials as sonar domes, etc. There is also a need to overview multi sensor array processing for many applications like finding direction of arrival and beam forming. Real time data acquisition is also a must for such applications
