Dalam makalah ini, pendekatan penyetempatan sumber bunyi yang mantap dicadangkan. Pendekatan ini mengekalkan prestasi yang baik walaupun ralat model wujud. Berbanding dengan kerja-kerja terdahulu dalam bidang ini, sumbangan kertas ini adalah seperti berikut. Pertama, model tatasusunan jalur lebar dan medan dekat yang dipertingkatkan dicadangkan. Ia mengambil kira perolehan tatasusunan, gangguan fasa dan berdasarkan kedudukan sebenar unsur-unsur. Ia boleh digunakan dalam tatasusunan geometri planar sewenang-wenangnya. Kedua, algoritma anggaran ralat model subruang dan algoritma Klasifikasi Isyarat Berbilang (W2D-MUSIC) Berwajaran 2 Dimensi dicadangkan. Algoritma anggaran ralat model subruang menganggarkan parameter yang tidak diketahui bagi model tatasusunan, iaitu, perolehan, gangguan fasa dan kedudukan elemen, dengan ketepatan yang tinggi. Prestasi algoritma ini dipertingkatkan dengan peningkatan SNR atau bilangan syot kilat. Algoritma W2D-MUSIC berdasarkan model tatasusunan yang dipertingkatkan dilaksanakan untuk mencari sumber bunyi. Kedua-dua algoritma ini menyusun pendekatan sumber bunyi yang teguh. Vektor stereng yang lebih tepat boleh disediakan untuk pemprosesan selanjutnya seperti algoritma pembentukan rasuk adaptif. Contoh berangka mengesahkan keberkesanan pendekatan yang dicadangkan ini.

Hua XIAO, Huai-Zong SHAO, Qi-Cong PENG, "A Robust Sound Source Localization Approach for Microphone Array with Model Errors" in IEICE TRANSACTIONS on Fundamentals,
vol. E91-A, no. 8, pp. 2062-2067, August 2008, doi: 10.1093/ietfec/e91-a.8.2062.
Abstract: In this paper, a robust sound source localization approach is proposed. The approach retains good performance even when model errors exist. Compared with previous work in this field, the contributions of this paper are as follows. First, an improved broad-band and near-field array model is proposed. It takes array gain, phase perturbations into account and is based on the actual positions of the elements. It can be used in arbitrary planar geometry arrays. Second, a subspace model errors estimation algorithm and a Weighted 2-Dimension Multiple Signal Classification (W2D-MUSIC) algorithm are proposed. The subspace model errors estimation algorithm estimates unknown parameters of the array model, i.e., gain, phase perturbations, and positions of the elements, with high accuracy. The performance of this algorithm is improved with the increasing of SNR or number of snapshots. The W2D-MUSIC algorithm based on the improved array model is implemented to locate sound sources. These two algorithms compose the robust sound source approach. The more accurate steering vectors can be provided for further processing such as adaptive beamforming algorithm. Numerical examples confirm effectiveness of this proposed approach.
