Shape identification using acoustic measurements: a numerical investigation using BIE and shape differentiation

Marc Bonnet

Résumé

The purpose of this paper is to study numerically the problem of identifying a rigid 3D finite body Ω imbedded in an infinite acoustical medium Ωe = R3 - Ω (wave velocity c). The cavity is subjected to a known harmonic incident pressure pI(x)exp(-iωt), which satisfies Helmholtz’ equation (Δ+k2)pI = 0 inside Ωe with k = ω/c.
