Problem of partial identification of unknown medium


Nazarov V.G.

2019, issue 1, Ñ. 43-62


Abstract
One consider the optimal control problem for stationary equations of acoustic waves diffraction on three-dimensional inclusion in unbounded homogeneous medium. The problem is to minimize $L^2$-deviation of pressure field in inclusion from the given. The control is the field source in the exterior medium.

Keywords:
radiography of a continuous medium, identification the chemical composition of a substance, singular value decomposition, calculation accuracy
