- Abstract
Nançay radio astronomy station teams are involved in several aspects of the Research and Development (R&D) for radio astronomy detectors and systems: i) Microelectronics: Low Noise Amplifiers (LNA), receiver on chip and system in package. The long-term goal is to provide sub-systems for the future Square Kilometer Array and its Pathfinders. A beamformer chip has been integrated in the FP6 SKADS dense aperture array technology demonstrator EMBRACE. Wide band SiGe LNAs are developed, beamformers with in-chip control are studied and more complex integrated receivers are designed for the european Aperture Array Verification Programme demonstrator. ii) Digital signal processing: EMBRACE beamforming has been implemented in the digital backend and RFI-mitigation oriented signal processing has been designed for realtime systems, including work for FP6 SKADS and FP7 PrepSKA. iii) A study of Phased Array Feeds has started in 2008, in order to study the radio electric properties of PAFs at the focus of large F/D telescopes, such as the Nançay Radio Telescope, as well as to test PAF systems in collaboration with the SPP/IRFU and LAL/IN2P3 laboratories.
