Description
We address the problem of emulating, in real time, the acoustic scattering from a stationaryobject under a moving emitter in three-dimensional space. Our approach employscontrol sources distributed over an artificial surface that surrounds the regionwhere the object is to be emulated. The control algorithm is based on the Kirchhoff– Helmholtz formulation, which is extended to the time domain to account for emittermotion and potentially nonstationary probing signals, and is combined with a dedicatedtime-dependent physical optics model. Reduction of the control-source extent is also exploredthrough the introduction of an equivalent internal surface.
