The problem of signal recovery from incomplete data is investigated in the context of phase-
space tomography. Particular emphasis is given to the case where only a limited number …

A linear spectral estimation technique, the PDFT algorithm, is used as part of a nonlinear
iterative reconstruction scheme to obtain improved radar images. The iterative PDFT …

The hyperspectral imaging technique described in [12] leads to the interesting problem of
reconstructing a three-dimensional data cube from measured data. This problem involves …

It is standard practice in signal processing to employ complex numbers whenever possible.
One of the main reasons for doing this is that it enables us to represent the important sine …

The situations of interest to us here can be summarized as follows: the data has been
obtained through some form of sensing; physical models, often simplified, describe how the …

In graduate school and for the first few years as an assistant professor I concentrated on
pure mathematics, mainly topology and functional analysis. Around 1979 I was drawn …
