Acoustic vector sensor

Our objective is to establish an acoustic vector sensor (AVS) system with a working configuration so data with regards to the beam pattern or other characteristics of the AVS can be determined. This report involves mainly 2 phases. In the first phase, we establish the hardware aspects of the AVS and...
