Phased Array Feed Development with the NTD Interferometer

Phased Array Feed Development with the
NTD Interferometer

Abstract:

A two dish interferometer has been built at the CSIRO Marsfield site to investigate phased array feed technologies for the next generation of radio telescopes, including MIRANdA and the SKA. Phased array feeds consisting of densely spaced focal plane arrays have the potential to provide contiguous wide fields of view and hence can greatly increase survey speeds. This interferometer is being used to investigate beamforming and calibration techniques. This talk will describe the instrument, some of the challenges in its development, proposed experiments and if available in time, some results.
