Abstract
The objective of this paper is to investigate sound scattering of a rigid scatterer using a two‐plane cylindrical acoustic holography method. A piston source, which is vibrating sinusoidally, illuminates a scatterer. The superimposed incident and scattered fields are measured in the near field of the scatterer using cylindrical acoustic holography. These two fields are decomposed in the wave‐vector domain in order to extract the scattered field. Numerical simulations are performed and the effect of various parameters is investigated. Specifically, the distance between the two‐holography cylinder, the sampling rate, and the aperture size are investigated in the field separation technique. In addition, experimental studies were conducted inside an anechoic chamber with a baffled loudspeaker as a source and a cylinder as a scatterer. The decomposed scattered field is then used to estimate the far‐field target strength. The near‐field scattering is also investigated.
