Technology Development Project• NSF-funded 2007-2011 for $12M

» Includes US contribution to the SPDO

• Complementary to and integrated with PrepSKA» EC-funded project 3+1 years, ~ same time frame as TDP

• Targets areas that bear strongly on cost and basic performance (Ae, Tsys, B, cross polarization, processing)

• Will deliver to the SKA project:» Technology options for LNSD array with broadband single-pixel

feeds» Costing of reflectors+mounts vs. D and fmax

» Optical designs that include both SP + PAF options (decision tree)» An SKA-optimized antenna, outfitted with feeds/receivers» Calibration and processing technology for LNSD arrays» Cost-modeling information for project decisions
