We studied source separation and source localization by nonlinear microphone array signal processing using higher dimensional map with kernels, and successfully developed high-resolution source localization using quadratic or higher-degree mapping. We showed that the covariance analysis of the mapping corresponds to the moment analysis with the order twice of the degree of the map, and the statistical property of the analysis in the source localization is clarified. It is ascertained that the proposed source localization has higher resolution and is more computationally efficient than the conventional methods.

研究了基于高维核映射的非线性麦克风阵列信号处理的声源分离和声源定位问题，成功地开发了基于二次或更高阶映射的高分辨率声源定位方法。我们证明了映射的协方差分析对应于映射阶数为2的矩分析，并阐明了该分析在源定位中的统计性质。它是确定的，建议的源定位具有更高的分辨率和更计算效率比传统的方法。
