Abstract
Aiming at the problem of acoustic vector DOAs estimation, according to the characters of acoustic vector sensor array and by combining with the MVDR algorithm, this paper puts forward a new algorithm of a-coustic vector sensor array DOAs estimation. This algorithm makes an addition of the data covariance matrix of vi-bration velocity control of acoustic vector sensor array to get a new covariance matrix. Then, by combining with it, and through the angle scanning process similar to V-MVDR algorithm, we realize the DOAs estimation. This algo-rithm does not need to know the amount of signal sources or characteristic value decomposition operation. It owns good DOAs estimation and resolution performance. The computer simulation results demonstrate the effectiveness of the proposed algorithm.关键词
