We consider the problem of selective imaging extended reflectors in waveguides using the response matrix of the scattered field obtained with an active array. Selective imaging amounts to being able to focus at the edges of a reflector, which typically give rise to weaker echoes than those coming from its main body. To this end, we propose a selective(More)
In this work we consider the problem of detecting and imaging extended reflectors submerged in the sea using acoustic waves. The sea is modeled as an acoustic waveguide consisting of a single water layer confined above by the sea surface and below by the seafloor, both assumed to be horizontal, i.e., our waveguide is an infinite strip of constant depth.(More)
