Paper Abstract

Future NASA missions will require wide field of view interferometric imaging in order to obtain high angular resolution over large fields of view. In particular, far-infrared and submillimeter missions will require interferometry because the long wavelengths drive large baselines in order to achieve reasonable spatial resolution and because the scientific motivations require large fields of view/ However, the requirement for a direct detection interferometer to cover a wide field of view over a wide spectral band has not been demonstrated. Because of this, we are developing a testbed for demonstrating wide field imaging interferometry algorithms that will allow us to evaluate the system issues and algorithms associated with this type of observatory. This paper will describe the drivers for this testbed, the design of this testbed, and the tests and algorithms we plan to run and demonstrate.
