Topic: A Variational Approach to Array Processing in the Presence of Uncertainties
By: Dmitry M. Malioutov (MIT), Mujdat Cetin (MIT), Alan S. Willsky (MIT)
Summary:
This research addresses sensor array processing problems by using an optimization-based framework. One such problem of interest is source localization in the presence of uncertainties in sensor locations. By exploiting an explicit model of the data collection geometry, sensor parameters, and statistically motivated constraints on the unknowns, the objective is to develop effective and robust variational schemes for information extraction.
