本研究旨在建立一套適用於近場聲源重建之聲學相機系統，透過理論推導、數值模擬與實驗設計，提出聲源定位之有效方法。首先從聲波波動方程、Green’s function與Kirchhoff積分理論出發，推導出聲場與聲源之數學關係，再透過數位化程序轉換成可用於數值計算之形式，建立完整的理論基礎。接續透過數值模擬，分析麥克風陣列的設計參數對聲源定位之影響。最後設計並建置實驗設備，測試聲學相機系統實務上的可行性，以期能有效提升近場聲源定位之應用潛力。;This study aims to develop an acoustic camera system suitable for near-field sound source reconstruction by proposing an effective localization method through theoretical derivation, numerical simulation, and experimental design. The research begins with the acoustic wave equation, Green’s function, and Kirchhoff integral theory to derive the mathematical relationship between the sound field and the sound source. This relationship is then digitized into a form suitable for numerical computation, thereby establishing a comprehensive theoretical foundation. Subsequently, numerical simulations are conducted to analyze the influence of microphone array design parameters on source localization performance. Finally, an experimental system is designed and implemented to evaluate the practical feasibility of the proposed acoustic camera, with the ultimate goal of enhancing its application potential in near-field sound source localization.
