Application of MVDR Beamforming to Noise Source Identification

Military Representative Office, Xi′an Dongfeng Instrument Factory, Xi′an 710065, China

摘要: 为了确定水下航行器主要辐射噪声源的特性, 对各噪声源进行量化排序, 本文研究了基于阵列信号处理的可应用于水下辐射噪声源识别的最小方差无畸变响应(MVDR)波束形成方法。使用16个水听器组成接收阵列并通过MVDR算法对采集数据进行解算, 实现对各噪声源方位和能级的识别。仿真和试验均证明了该方法的正确性和有效性。

Abstract: To identify the main noise sources and the related acoustic properties of the radiated noise from the underwater vehicle, a beamforming method of minimum variance distortionless response (MVDR) was proposed based on array signal processing for locating underwater radiated noise source. Noise signals are received by a receiving array of 16 hydrophones, and the data are analyzed with the beamforming method of MVDR. Simulations and experiments verify the validity and efficiency of the proposed method.
