中文摘要:采用速度传感器阵列提出了一种近场声源定位(距离和DOA估计)的新算法.与目前提出的其它算法相比,本文算法有以下几个优点:无需计算高阶累积量,从而有较低的计算量;能够实现参数估计的自动配对;阵元间隔无需限制在1/4波长内,并可以通过增加阵元间隔扩展阵列孔径,从而提高算法的参数估计精度.论文最后给出了仿真实验,验证了算法的定位性能.
外文摘要:A novel algorithm for near-field acoustic source localization,i.e.,range and Direction-of-Arrival(DOA) estimation by using a velocity sensor array is proposed in this paper.Compared with the existing algorithms,the proposed one has the following advantages:No need to compute higher-order cumulants,hence having lower computational loads;achieving automatic pairing in range and DOA estimation,and having no limitation of the intersensor spacing within 1/4-wavelength,and enabling to obtain higher estimation accuracy by increasing the intersensor spacing for a larger array aperture.Monte-Carlo simulations are presented to verify the efficacy of the proposed algorithm.
