Research on quantitative mechanism of Kirchhoff diffraction acoustical holography [PDF]
In the method of far-field acoustic holographic noise identification, the Kirchhoff formula has been widely used. Achievement of reconstruction is the outstanding advantage of acoustical holography over the widely-used beam-forming method. In this paper,
