Research on Two Array Processing Methods for Vector Sensor Array

Abstract

Abstract: For signal processing of an acoustic vector sensor array (AVSA), the extended method which keeps the coherence of AVSA and acoustic pressure sensor array can not show the particle velocity information obviously. Aimed at this problem, the AVSA datum covariance matrix of extended method was analyzed. The Bartlett bearing spectrum was derived. By using block matrix, the AVSA extended method can be coherent with combined method. The numerical simulation and lake experiment verify the theoretical results.

Key words: information processing, vector sensor array, beamforming, array processing, block matrix
