Tapio Helin, Matti Lassas, Lauri Oksanen +1
Passive imaging refers to problems where waves generated by unknown sources are recorded and used to image the medium through which they travel. The sources are typically modelled…

Inverse scattering for a random potential
Pedro Caro, Tapio Helin, Matti Lassas
In this paper we consider an inverse problem for the -dimensional random Schrödinger equation . We study the scattering of plane waves in the presence of a poten…

Large Noise in Variational Regularization
Martin Burger, Tapio Helin, Hanne Kekkonen
In this paper we consider variational regularization methods for inverse problems with large noise that is in general unbounded in the image space of the forward operator. We intro…
