Bistatic scattering from an array of regularly spaced cylinders
Acoustic scattering by an array regularly spaced cylinders in water tank has been investigated both theoretically and experimentally. A new scattering model for a group of cylinder is proposed based upon the infinite cylinder scattering model which uses scattering directivity and phase difference. It includes interference of scattered field between cylinders. The Target Strength (TS) is calculated by Integral Intensity Method. Our proposed model is capable of describing fluctuations of TS in scattering angles that the usual incoherent summation never produces such fluctuations. Also, the scattering patterns corresponding to various scattering angles and frequencies reflect the Bragg scattering.
