The reconstruction process of two-dimensional and three-dimensional sound-soft obstacles from a set of scattered field measurements is formulated as a linear filtering problem. Under coherent and incoherent insonification, the impulse response of the equivalent filter completely characterizes the acoustical imaging process. An energy-based criterion is proposed to describe the impulse response features in both cases. Numerical simulations are also presented, showing the better performance of the incoherent insonification.

Abstract
The reconstruction process of two-dimensional and three-dimensional sound-soft obstacles from a set of scattered field measurements is formulated as a linear filtering problem. Under coherent and incoherent insonification, the impulse response of the equivalent filter completely characterizes the acoustical imaging process. An energy-based criterion is proposed to describe the impulse response features in both cases. Numerical simulations are also presented, showing the better performance of the incoherent insonification.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
