Seafloor identification in sonar imagery via simulations of Helmholtz equations and discrete optimization

Bjorn Engquist, Christina Frederick, Quyen Huynh +1

We present a multiscale approach for identifying features in ocean beds by solving inverse problems in high frequency seafloor acoustics. The setting is based on Sound Navigation A…

An $L^{2} -$ stability estimate for periodic nonuniform sampling in higher dimensions

Christina Frederick

We consider sampling strategies for a class of multivariate bandlimited functions $f$ that have a spectrum consisting of disjoint frequency bands. Taking advantage of the special s…
