改进的SRP-PHAT声源定位方法

Sound Localization Method Using Modified SRP-PHAT Algorithm

  • 摘要: 基于联合可控响应功率和相位变换(SRP-PHAT)的传声器阵列声源定位方法是一种鲁棒的声源定位方法。该方法在弱噪声和适度混响的环境下,可以获得较精确的波达方向角(DOA)估计,但在低信噪比或强混响的环境下,该方法的性能并不理想,而且庞大的运算量也限制了其在实时定位系统中的应用。针对这两方面的问题,本文提出了一种改进的SRP-PHAT传声器阵列声源定位方法,从而使定位方法的运算量大大降低。仿真实验表明,改进的SRP-PHAT定位方法即使在噪声干扰较大和混响影响较严重的环境下,仍具有较高的定位精度。
