论文摘要
提出了一种在区域之间插值声传递函数（ATF）的方法，该方法考虑了ATF的物理性质和区域配置的方向性。大多数空间ATF插值方法仅限于接收器区域的估计。区域到区域ATF插值的内核方法可以从一组离散的ATF测量值中估算源和接收器区域的ATF。我们新制定了繁殖的内核希尔伯特空间和相关的内核函数，其中包含定向重量以提高插值精度。我们还研究了此内核函数的高参数优化方法。数值实验表明，所提出的方法在不使用方向加权的情况下优于该方法。
A method of interpolating the acoustic transfer function (ATF) between regions that takes into account both the physical properties of the ATF and the directionality of region configurations is proposed. Most spatial ATF interpolation methods are limited to estimation in the region of receivers. A kernel method for region-to-region ATF interpolation makes it possible to estimate the ATFs for both source and receiver regions from a discrete set of ATF measurements. We newly formulate the reproducing kernel Hilbert space and associated kernel function incorporating directional weight to enhance the interpolation accuracy. We also investigate hyperparameter optimization methods for this kernel function. Numerical experiments indicate that the proposed method outperforms the method without the use of directional weighting.
