近距離音場ホログラフィー法に関する研究 : 特異値分解による基準信号の選択

抄録

It is not always possible to apply nearfield acoustic holography (NAH) for the acoustic field composed of multiple incoherent sources. To apply NAH properly it is necessary to select optimal reference sets and divide mutually incoherent acoustic fields. In this work a new selection technique for optimal reference sets using singular value decomposition is presented and tested by using two speakers.
