Echolocating bats are thought to be able to create an image of their environment by emitting
pulses and analyzing the reflected echoes. In this paper, the theory of sparse
representations and its more recent further development into compressed sensing are
applied to this biosonar image formation task. Considering the target image representation
as sparse allows formulation of this inverse problem as a convex optimization problem for
which well defined and efficient solution methods have been established. The resulting …
